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?
