Quantify over all functions of a module

[Joerg Schuster]

Hello,

I want to refer to all functions of a module, say test2.py, without
having to manually enumerate them.

The following code comes closest to what I am trying to do. 
It does not work, because dir() does not return functions, but
function names as strings.

##### test2.py #####
def plus_2(_int):
    return _int + 2

def plus_3(_int):
    return _int + 3


#### test.py #####
#!/usr/bin/env python

import re
import test2

func_list = []

for func in dir(test2):
    test = re.search("^__", func)
    if not test:
        func_list.append(func)

for func in func_list:
    print apply(func, (2,))


I failed to find a solution by searching the net, probably because I
didn't know the right keywords. And I suppose that searching
would not be necessary, if I knew the right keywords.
