As a disincentive to casual use of this advanced feature,
there is no C<use English> long name for this variable.
-=item $^S
-
-The status returned by the last pipe close, back-tick (C<``>) command, or
-system() operator, in the native system format. On UNIX and UNIX-like
-systems, C<$^S> is a synonym for C<$?>. Elsewhere, C<$^S> can be used to
-determine aspects of child status that are system-specific. Check C<$^O>
-before using this variable. (Mnemonic: System-Specific Subprocess Status.
-Also known as $SYSTEM_CHILD_STATUS if you C<use English>.)

+now support "%i" as a synonym for "%d", and the "h" modifier.
+So "%hi" means "short integer in decimal", and "%ho" means
+"unsigned short integer as octal".

=item keys as an lvalue
As an lvalue, C<keys> allows you to increase the number of hash buckets
# implies:
A->VERSION(1.2);
-=item class()
-
-C<class> returns the class name of its object.
-
-=item is_instance()
-
-C<is_instance> returns true if its object is an instance of some
-class, false if its object is the class (package) itself. Example
-
- A->is_instance(); # False
-
- $var = 'A';
- $var->is_instance(); # False
-
- $ref = bless [], 'A';
- $ref->is_instance(); # True
-
-This can be useful for methods that wish to easily distinguish
-whether they were invoked as class or as instance methods.
-
- sub some_meth {
- my $classname = shift;
- if ($classname->is_instance()) {
- die "unexpectedly called as instance not class method";
- }
- .....
- }

+C<system> return genuine VMS status values instead of emulating POSIX;
+'exit', which makes C<exit> take a genuine VMS status value instead of
+assuming that C<exit 1> is an error; and 'time', which makes all times
+relative to the local time zone, in the VMS tradition.
