Boost.TypeTraits was heavily optimized and removed dependency on MPL
long time ago. I remember writing to this mailing list complaining about
the preprocessed size of type traits and how I was writing my own traits
to avoid it.
Later TypeTraits contributors did a wonderful job simplifying
Boost.TypeTraits and I'm thinking about switching back. The changelog in
boost.typeTraits reads:
Boost 1.60.0: Refactored traits to depend only on Boost.Config. Greatly
simplified code to improve readability and remove workarounds for old
compilers no longer supported.
Best,
Ion
