Alexander Belopolsky pointed out another nice aspect of this change:  after the 
change, let 'numerictype' be any of int, float, complex, Decimal or Fraction, 
and let 'x' be an instance of numerictype.  Then

numerictype(str(x))

recovers x exactly.

The consensus (so far) seems to be in favour of this change.  I'll leave it a 
few more days in case people haven't seen the python-dev thread yet, and then 
assuming that there's no dissent I'll commit.
