loris has asked for the wisdom of the Perl Monks concerning the following question:
Monks,
What would the best way of testing whether two regexes are equivalent? In particular, I am interested in seeing whether some apparently complex regex is actually equivalent to
.*I could obviously construct a set of strings which are somehow typical and see whether both regexes selected the same set, but that would demonstrate only rather limited equivalence and seems a bit of lame approach.
Thanks,
