Apart from the classic Regex::PreSuf, and, apparently (thanks Borisz) Regexp::Assemble, there's Regexp::List too, part of the Regexp::Optimizer package.

I wonder on the use of the availability of so many similar but not quite identical modules. I'm thinking that somehow, these should be unified into one, containing the best of all worlds, package.

Or maybe not, thanks to demerphq's recent work that got integrated into Perl 5.9.2 — and likely soon in a release for the general public, either 5.8.x or 5.10.x, too.
