Do you mean that I can detect the return type of operator[] at compile-time and do correct forwarding?
No, I mean you can detect when the return type of operator[] is the same as the reference type. Maybe if it isn't, you could turn off whatever you're doing with enable_if or something. Why is iterator_range using the iterator's operator[], anyway?
It seems very natural to be able to index a random access range, doesn't it. And how else would you implement that? Anyway, I guess I could do that check. Is it illegal for the iterators reference type to be a non-reference? -Thorsten
