It would have non-zero cost. There is a common idiom:

try: from foo import bar except ImportError: def bar(): ...

In this case you would need to try importing foo from other locations.

I wouldn't suggest going that far. The ImportError should always happen as before, just with a different error message. This case would still fail in an obscure way, but I don't think much can be done about that. -- Greg
