Huh.
You just convinced me that they should have separate names because they are really doing separate things; the issue of the same signature being a red-herring :)
I would suggest perhaps:
load_tests loads tests from a module
load_package_tests always loaded tests from a package.
Then if you want to load the package as a module and pass it to loadTestsFromModule, it's load_tests function (if any) will be called. Presumably, at this point, you know what you are doing. :) --- I'm projecting that I'd rather have two methods than to have two methods hidden inside of a test for the parameters on a single load_tests function (if I wanted to support his somewhat degenerate case; based on general experience since I haven't (and stuck on Python 2.4 wont' be) using this anytime soon.
Thanks for the discussion, I think it is an interesting extension mechanism, now that I understand it better. No further questions your honor.
