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.)
