+=head1 WARNING

+=for comment mst wrote this warning for MooseX::Declare, and ether adapted it for here:
+
+B<Warning:> Devel::Declare is a giant bag of crack
+originally implemented by mst with the goal of upsetting the perl core
+developers so much by its very existence that they implemented proper
+keyword handling in the core.
+
+As of perl5 version 14, this goal has been achieved, and modules such
+as L<Devel::CallParser>, L<Function::Parameters>, and L<Keyword::Simple> provide
+mechanisms to mangle perl syntax that don't require hallucinogenic
+drugs to interpret the error messages they produce.
+
+If you are using something that uses Devel::Declare, please for the love
+of kittens use something else:

 This builtin sets the full text of the current line of the source document.
+Beware that injecting a newline into the middle of the line is likely
+to fail in surprising ways.  Generally, Perl's parser can rely on the
+`current line' actually being only a single line.  Use other kinds of
+whitespace instead, in the code that you inject.
