Yes, but as there is an unit-test for it and that there is a comment
presenting it's use it could also be that nobody got the time to write a
documentation chapter about it.

Otherwise I have a similar implementation now, but I would find it bad
to duplicate implementations, as we anyway already depend on MPL in
Boost.Fusion.
