I'm surprised this works, because I would expect foo to not overload with bar's
functions, it has priority. I'm not sure how the current lookup rules work or
the rules for the new system about to be released (with all the import rule
fixes).

But in the final version, I would expect foo's foobar overload set to be
prioritized, because it was imported locally and has priority.

But we can "fix" the demonstration by removing the foobar(string) from foo, so
it wouldn't have been used as an overload set in the first place (similar to
the original code example).

In any case, the solution here is to do a selective import in a scope, which
works as expected. Alternatively, you can import both modules at the same scope
so they are used at the same priority.
