You can do this without fiddling with stack frames:
def bindfunction(f):
def bound_f(*args, **kwargs):
return f(bound_f, *args, **kwargs)
bound_f.__name__ = f.__name__
return bound_f
# Use like this:
@bindfunction
def factorial(this_function, n):
if n > 0:
return n * this_function(n - 1)
else:
return 1
# Interactively:
>>> factorial(5)
120
>>> fac = factorial
>>> factorial = "spam"
>>> fac(8)
40320
>>>
