I read the following from the regexp2 module for ACL.
- The new matcher uses Perl syntax, and is nearly feature compatible with Perl. Only a few obscure features have not been implemented.
- Speed: the new matcher was designed to be fast. On the CL-PPCRE test suite (with 1600+ tests) it is on average 30% faster than Perl.
Of course, the smartarse in me immediately responds,"What, the useful few obscure features?" I think every regexp feature in Perl can be called "obscure" by some party.
A related conversation:
Tosspot: "what's all this negative lookahead assertion crap? Must not be useful!"
Me: that would buy the 30% :-)
Tosspot: "I don't have to look ahead? Cool!"
