Thanks for the tip, I meant something else. Let's say that I want to write a function do-something. There could be 2 implementations: do-something-quickly and do-something-elegantly. The parameters are the same and there are no differences in their "interface". I would like to be able to call it by writing (do- something arg) in my code and specify which implementation I want to use somewhere else (in the configuration part of the code).
