Perl: the Markov chain saw

First of all, the things that are promised for 5.10. :) These include:
  • defined or: // and //=
  • speed improvements in regexes as promised (and implemented) by demerphq
  • recursive regexes! (ditto)

Aside from that, I'd like to see support for matching regexes across boundaries for partially loaded buffers. That would ease processing files in blocks of a few k each, instead of having to load the entire file into a string.

As an example: say you're looking for a word "SELECT" and the buffer contains:

my $sth = $dbh->prepare('SEL
It's possible that it would have matched "SELECT" if the buffer wasn't cut off.

I'd like regexes to be able to catch that. Automatically.

I don't really care how it's done, but I personally favor a system that takes some action (die, set a variable, call a callback sub) when the lookahead "touches" the back end of the buffer. (I call that the "electric fence" approach: touch it and you're dead.)

      Should cpanminus be part of the standard Perl release?
