Re: [boost] A proposal for the creation of a new module, Core Type Traits

These two problems could be avoided if we were to have core type traits whose interface consisted solely of a member integral constant called "value", without any other required members or base classes, and which were only allowed to depend on Config or StaticAssert.

I'm less keen on this because it fractures the lib into two conceptually different parts. Let me mess around with some code and see if something better is possible. John.
