9813,[boost] [fusion] constexpr support,gonzalobg88@…,Joel de Guzman,"Boost.MPL and Boost.Fusion are very useful inside C++14 relaxed constexpr functions. However, this doesn't work out of the box since constexpr functions can only call other constexpr functions. 

I have started to mark fusion and mpl functions and types as constexpr within my local Boost copy. This task is pretty big so I am only doing it for the parts of the library that I need to use within constexpr functions.

It would be nice to know what is the best way to proceed (e.g. incremental patches until full support is achieved vs a single patch that enables constexpr support). ",Feature Requests,closed,To Be Determined,fusion,Boost 1.55.0,Problem,fixed,constexpr,
