[Python-ideas] add variable "__this_func__" inside all functions' locals

How a function refer itself? def f(): f() # fine... really??? consider these situations: 1) decorator @xxx def f():... # how can I access the wrapped version? 2) replace by other def f(): f() # call second!! a = T(f) # to call first def f():... 3) refactor: rename function # first version def f():f() ------------------- # second version, wrap it def f(): log(); try: # to avoid indent _f_impl() except... def _f_impl(): _f_impl() # hadnot we rename it! solution: # add __this_func__ class C: @xxxx def f(self): self.f() __class__.f(self) __this_func__(self)
