I'm afraid you're going to be disappointed. There is no possible way for 
one() and two() as shown above to report different names, because they 
are the same function object.

py> two = lambda : "one"
py> one = two
py> one is two
True
py> one, two
(<function <lambda> at 0xb7abd92c>, <function <lambda> at 0xb7abd92c>)
