You might try to deprecate reduce() though.  It's useless.

Not so sure.  It's very handy in converting numbers to weird-radix or
mixed-radix systems.  E.g. it's a natural for converting posix
timestamps to broken-out times, and e.g.
<CVSROOT>/nondist/sandbox/datetime/datetime.py is full of it.

Unfortunately the function is needed as the API to 3-arg pow() --
which doesn't easily fit in the math library since it's not a floating
point thing.

You can write something using urllib that pulls things down, and I
recommend using the tokenizer module to do the parsing -- much slower
than grep, but doesn't get confused by comments etc.  See
Tools/scripts/finddiv.py for an example.
