Quantifiers in (?(DEFINE)...) #16106
Comments
From @AbigailCreated by @AbigailConsider this pattern: my $pat = qr { This matches a string of digits, and Perl doesn't complain. Now, let's make a small change; instead of trying to match my $pat = qr { This pattern works, but a warning is issued: Quantifier unexpected on zero-length expression in regex m/ The same happens if we replace {4} with {4,4} or {2,4}, and disappears This problem is still present in blead.
