I dont know that I agree that Perl should die. We warn instead:
$ ./perl -we'qr/(?-p)foo/'
Useless use of (?-p) in regex; marked by <-- HERE in m/(?-p <-- HERE
)foo/ at -e line 1.
Given the mild consequences of this type of mistake I think warnings
are sufficient.
Unless someone strongly disagrees I would like to close this ticket
as "wont fix".
Thanks for the report though!
