Re: No recursion depth limit?

I don't know

I think you might be thinking of regex recursive pattern recursion limit

Research

A place to look ( perldeltas )

Another place http://perl5.git.perl.org/perl.git?a=search&h=HEAD&st=grep&s=recursion -> http://perl5.git.perl.org/perl.git/blob?f=t/op/recurse.t ( # check ok for recursion depth > 65536)

And another http://perl5.git.perl.org/perl.git?a=search&h=HEAD&st=free&s=recursion

And another site:http://www.nntp.perl.org/group/perl.perl5.porters/ maximum recursion

And another https://rt.perl.org/Public/Search/Simple.html?q=+recursion

site:metacpan.org maximum recursion , site:search.cpan.org maximum recursion

maximum recursion -> Recursion is of unlimited depth.

So in summary, there is a regex recursive pattern limit, configurable
