Hi,
I have to admit I don't exactly understand how the backtracking words are working, but my understanding is that (a) should be done by (*PRUNE) according to
http://perldoc.perl.org/perlre.html . Therefore I would vote to (b) option.
Regards,
Zoltan

Consider the pattern ^A(B(*THEN)C), where A, B, and C are >

(a) the entire match should fail, or>
(b) the matching should backtrack into A? >
