It would be Which version of Perl am I compiled with? But $?perlversion

Again, which OS am I compiled on, or at best, which OS does the compiler

Therefore should:

Speaking of subs, and especially recursive ones which have been mentioned
en passant earlier, I have another question of mine: I know that in the
vast majority of cases this won't be useful in any way, but in the body of
a (possibly anonymous) sub/block, will there be some sort of identifier to
