B::CC is a little better. It produces slightly more idiomatic code.

I wouldn't use it in a production environment, though. The only time I've ever compiled Perl was using perl2exe, and that was simply a one-shot filter application that had to be run on a completely different platform approximately once every three weeks.

Most of these 'compilers' just produce a wrapper around a working Perl environment, anyway. How else would they handle eval()?
