Consider:

a = A()
with a:
   b = c
   
What does c refer to? Is it a.c or some global c? There's no way to tell.
It might even change from time to time. I'm assuming that c would refer to
a.c iff a has an attribute called c, and to another variable otherwise. But
even the fact that I have to make such an assumption shows that this should
not be Python... Be explicit as much as possible.
