The current state of perl is that the limit in 5.30 has been doubled so you don't hit the recursion limit until 2**16. Also, some parts of this ticket (and those merged to it) have been fixed, so that if you give an unbounded quantifier, it actually uses the machine platform limit. If you do specify an upper bound, it must a max of 2**16-1. -- Karl Williamson --- via perlbug: queue: perl5 status: open https://rt.perl.org/Ticket/Display.html?id=18268
