Guido requested this change so that the Decimal repr would match the style used elsewhere (i.e. str(7) --> '7').

A quick hack is to monkey patch the decimal module:
>>> import decimal
>>> decimal.Decimal.__repr__ = lambda s: 'Decimal("%s")' % str(s)
A better fix is to amend to doctests to not rely on the __repr__ format.
>>> print Decimal('7.1')
