If the C</g> option is not used, C<m//> in list context returns a
list consisting of the subexpressions matched by the parentheses in the
-pattern, that is, (C<$1>, C<$2>, C<$3>...). (Note that here C<$1> etc. are
-also set, and that this differs from Perl 4's behavior.) When there are
-no parentheses in the pattern, the return value is the list C<(1)> for
-success. With or without parentheses, an empty list is returned upon
-failure.

Examples:
Any non-whitespace delimiter may replace the slashes. Add space after
the C<s> when using a character allowed in identifiers. If single quotes
are used, no interpretation is done on the replacement string (the C</e>

as normal delimiters; the replacement text is not evaluated as a command.
If the PATTERN is delimited by bracketing quotes, the REPLACEMENT has
its own pair of quotes, which may or may not be bracketing quotes, for example,

many Unix shells and C<&> on the Windows NT C<cmd> shell).
