There has been a long discussion on this indeterminate form of exponentials previously - See More Fun with Zero!, in particular the replies from ariels and tilly.

Thanks, that's quite interesting! Unfortunately, I don't understand most of the mathematical explanations (tilly++ for explaining the thing in English) and I can't find if 0**0 == 1 in Perl is coincidental or defined behaviour (ie. can I depend on 0**0 to be 1?).
