Just wanted to clarify, because I know that the intellectually deficient
amongst you will say that isinstance is better than using __class__...

In this case isinstance isnt desirable because it will catch
instances of any objects that inherit A, not just instances of A. Observe:

class A: pass
class B(A): pass

a = A()
b = A()
c = A()
d = B()

>>> [x for x,y in locals().items() if isinstance(y,A)]
['a', 'c', 'b', 'd']

>>> [x for x,y in locals().items() if
... hasattr(y,"__class__") and y.__class__ == A]
['a', 'c', 'b']
