+=head1 NAME
+
+XS::APItest::KeywordRPN - write arithmetic expressions in RPN
+
+=head1 SYNOPSIS
+
+ use XS::APItest::KeywordRPN qw(rpn calcrpn);
+
+ $triangle = rpn($n $n 1 + * 2 /);
+
+ calcrpn $triangle { $n $n 1 + * 2 / }
+
+=head1 DESCRIPTION
+
+This module supplies plugged-in keywords, using the new mechanism in Perl
+5.11.2, that allow arithmetic to be expressed in reverse Polish notation,
+in an otherwise Perl program. This module has serious limitations and
+is not intended for real use: its purpose is only to test the keyword
+plugin mechanism. For that purpose it is part of the Perl core source
+distribution, and is not meant to be installed.
+
+=head2 RPN expression syntax
+
+Tokens of an RPN expression may be separated by whitespace, but such
+separation is usually not required. It is required only where unseparated
+tokens would look like a longer token. For example, C<12 34 +> can be
+written as C<12 34+>, but not as C<1234 +>.
+
+An RPN expression may be any of:
+
+=over
+
+=item C<1234>
+
+A sequence of digits is an unsigned decimal literal number.
+
+=item C<$foo>
+
+An alphanumeric name preceded by dollar sign refers to a Perl scalar
+variable. Only variables declared with C<my> or C<state> are supported.
+If the variable's value is not a native integer, it will be converted
+to an integer, by Perl's usual mechanisms, at the time it is evaluated.
+
+=item I<A> I<B> C<+>
+
+Sum of I<A> and I<B>.
+
+=item I<A> I<B> C<->
+
+Difference of I<A> and I<B>, the result of subtracting I<B> from I<A>.
+
+=item I<A> I<B> C<*>
+
+Product of I<A> and I<B>.
+
+=item I<A> I<B> C</>
+
+Quotient when I<A> is divided by I<B>, rounded towards zero.
+Division by zero generates an exception.
+
+=item I<A> I<B> C<%>
+
+Remainder when I<A> is divided by I<B> with the quotient rounded towards zero.
+Division by zero generates an exception.
+
+=back
+
+Because the arithmetic operators all have fixed arity and are postfixed,
+there is no need for operator precedence, nor for a grouping operator
+to override precedence. This is half of the point of RPN.
+
+An RPN expression can also be interpreted in another way, as a sequence
+of operations on a stack, one operation per token. A literal or variable
+token pushes a value onto the stack. A binary operator pulls two items
+off the stack, performs a calculation with them, and pushes the result
+back onto the stack. The stack starts out empty, and at the end of the
+expression there must be exactly one value left on the stack.

+
+=head1 OPERATORS
+
+These are the operators being added to the Perl language.
+
+=over
+
+=item rpn(EXPRESSION)
+
+This construct is a Perl expression. I<EXPRESSION> must be an RPN
+arithmetic expression, as described above. The RPN expression is
+evaluated, and its value is returned as the value of the Perl expression.
+
+=item calcrpn VARIABLE { EXPRESSION }
+
+This construct is a complete Perl statement. (No semicolon should
+follow the closing brace.) I<VARIABLE> must be a Perl scalar C<my>
+variable, and I<EXPRESSION> must be an RPN arithmetic expression as
+described above. The RPN expression is evaluated, and its value is
+assigned to the variable.
+
+=back
+
+=head1 BUGS
+
+This module only performs arithmetic on native integers, and only a
+small subset of the arithmetic operations that Perl offers. This is
+due to it being intended only for demonstration and test purposes.
+
+The RPN parser is liable to leak memory when a parse error occurs.
+It doesn't leak on success, however.
+
+The linkage with Perl's lexer is liable to fail when an RPN expression
+is spread across multiple lines.

+NAME
+
+XS::APItest::KeywordRPN - write arithmetic expressions in RPN
+
+DESCRIPTION
+
+This module supplies plugged-in keywords, using the new mechanism in Perl
+5.11.2, that allow arithmetic to be expressed in reverse Polish notation,
+in an otherwise Perl program. This module has serious limitations and
+is not intended for real use: its purpose is only to test the keyword
+plugin mechanism. For that purpose it is part of the Perl core source
+distribution, and is not meant to be installed.

+
+Function pointer, pointing at a function used to handle extended keywords.
+The function should be declared as
+
+ int keyword_plugin_function(pTHX_
+ char *keyword_ptr, STRLEN keyword_len,
+ OP **op_ptr)
+
+The function is called from the tokeniser, whenever a possible keyword
+is seen. C<keyword_ptr> points at the word in the parser's input
+buffer, and C<keyword_len> gives its length; it is not null-terminated.
+The function is expected to examine the word, and possibly other state
+such as L<%^H|perlvar/%^H>, to decide whether it wants to handle it
+as an extended keyword. If it does not, the function should return
+C<KEYWORD_PLUGIN_DECLINE>, and the normal parser process will continue.
+
+If the function wants to handle the keyword, it first must
+parse anything following the keyword that is part of the syntax
+introduced by the keyword. The lexer interface is poorly documented.
+Broadly speaking, parsing needs to look at the buffer that extends
+from C<PL_parser-E<gt>bufptr> to C<PL_parser-E<gt>bufend>, and
+C<PL_parser-E<gt>bufptr> must be advanced across whatever text is
+consumed by the parsing process. The buffer end is not necessarily the
+real end of the input text, but refilling the buffer is too complicated
+to discuss here. See L<Devel::Declare> for some parsing experience,
+and hope for more core support in a future version of Perl.
+
+When a keyword is being handled, the plugin function must build
+a tree of C<OP> structures, representing the code that was parsed.
+The root of the tree must be stored in C<*op_ptr>. The function then
+returns a contant indicating the syntactic role of the construct that
+it has parsed: C<KEYWORD_PLUGIN_STMT> if it is a complete statement, or
+C<KEYWORD_PLUGIN_EXPR> if it is an expression. Note that a statement
+construct cannot be used inside an expression (except via C<do BLOCK>
+and similar), and an expression is not a complete statement (it requires
+at least a terminating semicolon).
+
+When a keyword is handled, the plugin function may also have
+(compile-time) side effects. It may modify C<%^H>, define functions, and
+so on. Typically, if side effects are the main purpose of a handler,
+it does not wish to generate any ops to be included in the normal
+compilation. In this case it is still required to supply an op tree,
+but it suffices to generate a single null op.
+
+That's how the C<*PL_keyword_plugin> function needs to behave overall.
+Conventionally, however, one does not completely replace the existing
+handler function. Instead, take a copy of C<PL_keyword_plugin> before
+assigning your own function pointer to it. Your handler function should
+look for keywords that it is interested in and handle those. Where it
+is not interested, it should call the saved plugin function, passing on
+the arguments it received. Thus C<PL_keyword_plugin> actually points
+at a chain of handler functions, all of which have an opportunity to
+handle keywords, and only the last function in the chain (built into
+the Perl core) will normally return C<KEYWORD_PLUGIN_DECLINE>.

+=head2 Pluggable keywords
+
+Extension modules can now cleanly hook into the Perl parser to define new
+kinds of keyword-headed expression and compound statement. The syntax
+following the keyword is defined entirely by the extension. This allow
+a completely non-Perl sublanguage to be parsed inline, with the right
+ops cleanly generated.
+
+This feature is currently considered experimental, and using it to do
+anything interesting is difficult. Many necessary supporting facilities,
+such as the lexer and the pad system, can only be accessed through
+unsupported internal interfaces. It is intended that the Perl 5.13
+development cycle will see the addition of clean, supported interfaces
+for many of these functions. In Perl 5.12 most uses of pluggable keywords
+will be via L<Devel::Declare>.
+
+See L<perlapi/PL_keyword_plugin> for the mechanism. The Perl core source
+distribution also includes a new module L<XS::APItest::KeywordRPN>, which
+implements reverse Polish notation arithmetic via pluggable keywords.
+This module is mainly used for test purposes, and is not normally
+installed, but also serves as an example of how to use the new mechanism.
