Modules are not callable because their class, module, has no __call__
instance method. But (in 3.0, which is all I will check) you can
subclass module and add one.
>>> m = type(__builtins__)
>>> m
<class 'module'>
>>> dir(m)
['__class__', '__delattr__', '__dict__', '__doc__', '__eq__',
'__format__', '__ge__', '__getattribute__', '__gt__', '__hash__',
'__init__', '__le__', '__lt__', '__ne__', '__new__', '__reduce__',
'__reduce_ex__', '__repr__', '__setattr__', '__sizeof__', '__str__',
'__subclasshook__']
>>> class m2(m):
def __call__(self, *args, **kwds):
print(self, args, kwds)
>>> mod = m2('mod') # only arg required by module.__init__
>>> mod(1,2,3,a=4,b=5)
<module 'mod' (built-in)> (1, 2, 3) {'a': 4, 'b': 5}
>>> mod # did not override __repr__
<module 'mod' (built-in)>
So, roll your own to your taste.
