Hi,
8. [...] Saying 0**0 is undefined seems reasonable, but why 0**y? I agree on 0**y being 0 (not undefined), but why should 0**0 be undefined? x**0 := 1, by convention. Of course this is a still ongoing debate (regarding analysis of functions etc.), but the most usefull approach for /any/ programming language (and BTW for many mathematical proofs, too).
