Ah, I think maybe I see what you were going for there. Yes, that might help a little bit in some cases actually, such as if some Element is passed to Python's built-in round(), but that could also be handled on a case-by-case basis... I don't think we necessarily need or want to remove Sage's own round() function though. As I wrote previously, it's worth keeping for the better docs alone. It also doesn't help with the question of what to do with RealNumber.__round__() -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
