I'd say this was an argumentum ad populum, only you didn't cite anything
that shows the "many" you claim you speak for.

Are you sure that's not just you?

Just off the top of my head, we have several solutions for this:
1) Rebinding imports
import foo as foo2
2) Namespace packages
import mypackage.foo
3) Filepath imports (deprecated in 3.4 but under discussion for
reprecation or replacement)
import importlib.machinery
loader = importlib.machinery.SourceFileLoader("module.name",
"/path /to/file.py")
foo = loader.load_module()
foo.MyClass()
4) Virtual environments
In before "but WHY so MANY different WAYS OMG PYTHON you M.F.P.O.S.":
because they offer flexibility.

They're also clear indication of bad design. That's not something Python
should explicitly set out to support.

Well sure, if your reaction to things you don't understand is to rant
against them instead of asking questions, then I can see how that would
be true.
Also: citation needed.

Is this the sequel to "Too Many Cooks"? Awesome.

There's your problem right there: a language conforms to its
specification, not your random expectation.
I'm eager to see how you resolve your concerns in RickPython3000.
