This was the way things worked in Python 2, I believe.Another proposal is to make this code a syntax error, because it's confusing either way. (For what it's worth, that would be my preference.)Concerning this two options it looks like me and Serhiy like the first one, Paul is undecided (), and Antoine is in favor of option 2.
While that may be the right thing to do, it's a silent change in semantics, which I find pretty disturbing -- how would people debug such a failure? That's why I think we should deprecate or hard break it for at least one release.
