Hello


I'm not sure I'm in the right place, however my question is somehow
related to an interpreter. Not a "must do", rather a "wanna know". So,
my question is: how would a regular expression that matches a regular
expression look like ?


Given a string like "$myFoo =~ /regexp/" *, I want to match the /
regexp/ part. I can't just use something like /\/[^\/]*\// because my /
regexp/ can be /^http:\/\// and it will only return "/^http:/".


* no, I'm not writing a Perl interpreter :-)
