I've been meaning to say this for a few days, but finally I get round
to saying that this particular argument bothers me; Python isn't a
language you program with a reference manual open at all times
(unlike, say, C++) - and this IMHO is a good thing. This particular
change probably isn't too stressful, but I slightly fear more onerous
restrictions might be lurking in the ref manual to be whipped out when
we next get comfortable with the language.
(Of course SML does have its weaknesses, but by comparison, a
discussion of C++'s strengths and flaws always sounds like an
argument about whether one should face north or east when one
is sacrificing one's goat to the rain god.) -- Thant Tessman
