Ack. In that case we should clearly document what the `_Tp` in `__make_transparent<_Tp, _Compare>` is. At the moment it's not super clear; should it be the type of the key contained in the map or should it be the type of the key that we're using to perform the search? What we document in `__make_transparent` should make that obvious.
