I meant PCRE.  It's still used by Io, J, CMUCL, and Lua, to name a
few, though it's an option in some of those languages (that is, there
are multiple regex packages to choose from).  And it was standard in
Python for a while (but no more).

In any case, I am glad that the regular expression module for Erlang
isn't as over-the-top insane as regular expressions in Perl.
