Search pattern not terminated

(F) The lexer couldn't find the final delimiter of a // or m{} construct. Remember that bracketing delimiters count nesting level. Missing the leading $ from a variable $m may cause this error.

Note that since Perl 5.9.0 a // can also be the defined-or construct, not just the empty search pattern. Therefore code written in Perl 5.9.0 or later that uses the // as the defined-or can be misparsed by pre-5.9.0 Perls as a non-terminated search pattern.
