In any other convention, I would have to loop over the internal bins and then handle the extra bins outside of the loop.

I find this to be the cleanest solution, as the under-/overflow bins are special anyways. If we wish to iterator over all bins, then you could provide a special iterator for that. Hopefully it would be possible reuse the existing iterator and simply provide new begin/end functions. If we wish to index into the under-/overflow bins, then you could provide an operator[] that overloads on enum types for the underflow and overflow bins (as suggested in my formal review.)
