Or if you don't care, or want to intercept invalid calls.  Interestingly,
the OP's example is the beginning of a possible debug wrapper usage where
one either does not have a function's code or does not want to modify it
directly.  Possible example:

_f_orig = f
def f(*largs, **kargs):
  print 'f called with' largs, 'and', kargs
  f(*largs, **kargs)
