Wow - what a cool use of local variables in regex code expressions! And it shows, IMO by far the best way to create complex regexes: machine generate them a bit at a time for good comprehension.

This sort of approach to backtracking fits naturally into the perl6 regex overhaul. Although ease of parsing complex grammars will be the most obvious benefit of perl6 rules, I think associated temp variables synchronized with backtracking will provide a powerful tool for algorithms such as this.

Thanks Abigail-II!

Are you posting in the right place? Check out Where do I post X? to know for sure.
Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
