Wasn't even trying to obfuscate. Just trying to minimize the use of vertical space by compressing maximum functionality into a small space while maintaining clarity. 
$stoken = 'STRING';
$ltoken = 'LITERAL';

# sub out literals, strings, and one-line comments
    s#('([^'\\]|\\.)*')                     |
      (L?"([^"\\]|\\.)*")                   |
      ((_T|_TEXT)\("([^"\\]|\\.)*"\))       |
      (/\*([^*]|\*+[^/*])*\*+/)             |
      (//[^\n]*)                    #
            ( ( defined $1 || defined $5 ) && $ltoken ) ||
              ( defined $3 && $stoken )
                                    #gexo;
