Judging by the example code which you quoted, I would guess that these
things have never been optimized. That is, optimized for compilation speed.
Peter has done considerable work in this area for Boost.MP11 and I think
Boost.Variant2 (?) which he spent time optimizing. Here is an example:

https://github.com/boostorg/mp11/blob/develop/include/boost/mp11/detail/mp_append.hpp

It may be possible to breath new performance improvements into those
libraries today, by adopting some of Peter's techniques, and this is
orthogonal to the question of obsolete libraries !

Thanks
