Re: Self-recognizing programs and regular expressions

Nice!

In my first draft of the problem I had specifically disallowed
infinitely long strings (afterall "print "print "print ... is not a
valid quine) but I must have foolishly dropped it in one of the
revisions. 

I'll accept infinitely long solutions as soon as we have a cpan module
that allows infinitely long regex.  :)
