We need not care other functions, just the "current" one. Other functions are definitely out of our control. My last example distinguish 3 cases: self.f() # object/overloaded version __class__.f(self) # decorated version __this_func__(self) # prime version At 2017-03-01 09:30:56, "Matthias welp" <boekewurm@gmail.com> wrote:

How a function refer itself? def f(): f() # fine... really???
I understand your question as the following: "Should functions be allowed to point to themselves/the as of construction time unbound variable in the function body, as they are not yet bound to a variable at construction time"
I think they should be allowed, as only when the function is executed the variable lookups (and therefore function lookups) should happen. Object.function() would have, well, interesting behaviour if you were to pre-insert all function calls in the code:
d = {'hello': 'world'} def f(): d.keys = lambda: {} print(d.keys())
would result in "['keys']" being printed, while you explicitly said that the keys method on variable d has to return an empty dict.
I hope this helps you with your question.
