Forgive me if this is not the right place to direct this sort of
question....
Why do we have
(?(zero-width-assertion)yes-pattern|no-pattern)
Isn't this identical to
(?:(zero-width-assertion)yes-pattern|no-pattern)
The only typing that is saved appears to be the colon. Otherwise this is
nothing new. Right?
