Funny. Python 1.5.2 used the _same_ C library by Philip Hazel. :-) Given the fact this library builds DFA's instead of NFA's, Python ought to be faster than Perl. :-) Note also, Python 2.0 uses a modified library which does something PCRE-OCaml cannot: it works with Unicode characters (supposedly). I do have a question though: is it possible to build a Str compatible interface to PCRE-Ocaml, and then make them both a standard part of the distribution?
