really? what if "a" is a froob?
class froob:
def __add__(self, other):
return other + 1.0
def __dotadd__(self, other):
return other + 1.0
>>> a =3D froob()
>>> print 3+a()
4.0
>>> print 3.+a()
SyntaxError: sorry, that doesn't make sense. try inserting a space.
>>> print 3. + a()
4.0
>>> print 3.0+a()
4.0
</F>
