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)
