Thanks, I'll take a look at those tests, but they're likely
to have a lot of duplicates with the existing test suite.

What Felix is looking for, however, is a benchmark.
CL-PPCRE used to have benchmarks, but they weren't very
good, and don't even seem to be available anymore.  The
shootout benchmark is a joke.

I'll be working on comprehensive benchmarks for the next
release of irregex.  In the meantime, I think a simple
collection of common regular expressions and usage patterns
in existing Chicken code would help to reassure people :)
