You can just base the type off of some nested type that's created by the
macro. Also, the CRTP approach handles this fine as well (you just form the
type using the child parameter).

That said, I, too, have used a hand-rolled macro version in the past. Given
that so many of us have done either the CRTP or macro approach at some
point, something should probably make its way into boost, outside of detail.
