in thread Testing a string for a range of characters

Hmm, good suggestion, but these are the results I get -

Benchmark: timing 10000000 iterations of comp, exist, regex, regexo... comp: 53 wallclock secs (53.96 usr + 0.00 sys = 53.96 CPU) exist: 49 wallclock secs (49.23 usr + 0.00 sys = 49.23 CPU) regex: 78 wallclock secs (77.40 usr + 0.00 sys = 77.40 CPU) regexo: 78 wallclock secs (77.12 usr + 0.00 sys = 77.12 CPU)

As you can see regexo isn't showing much difference. Could this be because I'm using /^[A..Z]$/o instead of your suggested /^[A-Z]$/o, or are they functionally equivalent?
