The time machine strikes again. We have not one but THREE ways of doing
so (although two are alternate ways of spelling the same thing):
py> def func():
... return 
Sure, but this requires that you actually return something "unpackable" from the function. As David Mertz pointed out, functions always return a single value, but that value may or may not be unpackable.
So the OP's desire, that you could extend a function that was originally written returning a single scalar value to instead return multiple values, and have code that expected a single value still work the same simply isn't possible (without other major changes to Python).
