This seems to confirm my suspicion that the do_something_with function
doesn't actually need a reference to the module, it only needs a
reference to the function to call.

Maybe your hurdle is how to obtain a reference to a function from the
current module when all you have is the name of the function in a
string. The answer to that would be "globals()[funcname]".
