Differences between class and function decorator

[mk]

Hello everyone,

I rewrote an example someone posted here recently from:
def new_meth(*args, **kwargs):
print method.func_name
return method(*args, **kwargs)
return new_meth
def f2():
pass

f2


...to:

def __init__(self, func):
self.name = func.func_name
self.func = func
def __call__(self):
print self.name
return self.func

def f():
pass
f
<function f at 0x017CDA70>

Note that function decorator returned None, while class decorator
returned function.

Why the difference in behavior? After all, print_method_name decorator
also returns a function (well it's a new function but still a function)?

Regards,
mk
