Ack. I guess spending two days trying to grok yacc and Parse::Yapp led me to choose to do it the hard way. Thanks for a healthy does of simplicity.
Unfortunately, the following regexp break your very good idea:
That only means your code needs at least one capture:
This passes my whole test suite, expect for this regexp:
Which dies horribly with the message:
Unmatched ( in regex; marked by <-- HERE in m/(?:(( <-- HERE ?-xism:(?x) # (comment) (?-x) # (capture) (?x) # (comment))))?/
So, $regex compiles, but qr/(?:($regex))?/ doesn't? I'm lost.
