In fact, I foresee a combo of 2,3 and some expert system somewhere producing the first sentient perl program. ;-) Ed ( ps: As for the 'rexen' concept of matching stuff other than characters, hell, that's a *wonderful* idea. And if you turned the regex around so that you could (in a meaningful way) make productions from it for stuff other than characters, you could make random http requests, music, GUI requests/interactions database connections and so forth. Its a code testers' dream... Now, just got to think of the syntax for it.. how to make it usable. )Thread Previous | Thread Next
