There's no way that it could distinguish between an explicit StopIteration and an implicit one, so it treats them the same way. If a comprehension is supposed to be the same as list(genexp) it should act like list--or like any other iteration mechanism you can write in Python or even in C--rather than acting magically as it currently does.

Damnit, you're so obviously right. Yeah, fine. Whatever.
