japhy has asked for the wisdom of the Perl Monks concerning the following question:
(I'm pleased to see 'sexeger' showing up in other places -- apparently, Pete's article and my personal research have touched people's lives!)
I'd rather not write an introductory article, but rather one focusing either on regex reversal as a practice, my upcoming Regexp::Parser module, or a specific facet of Perl's regexes, such as global matching and the /gc modifiers, or using code evaluations or delayed execution blocks ((?{...}) and (??{...})).
I'm open for suggestions, and if I had a larger ego, I'd ask vroom to make this the site poll. But I'm humble, so just /msg me or, more usefully, reply to this node with an idea that others can ++ or reply to. Perhaps I'll go by popularity of the node. I don't know. Help me help you.
