I've read your previous post, and I don't understand why you consider it
unfeasible. The user provides a function name in a config file, which
gives you funcname as a string. You already know which module it comes
from (you didn't specify how, but all your examples show that). Carsten is
simply showing you how to get the function from the function name without
the nasty hack using sys._getframe. Why is in unfeasible?
