Exactly. That is what I think should really happen here.

I will try to find a spare time to some job in the area. I am planning API like this (in terms of Python 2.x with anydbm):

dbm.something module

import anydbm anydbm.register('something', whichdb_test_function)

whichdb_test_function is not required - whichdb module can provide a generic test function:

def generic_test(filename, module_name): module = import(module_name) try: module.open(filename) except: return False else: return True

Oleg.

       Programmers don't die, they just GOSUB without RETURN.
