Re: [boost] [type_traits][core] modularisation and moving stuff about (again)

Yes. If that restriction is something we're open to relaxing now, that works. Both would allow use of BOOST_IS_FINAL and BOOST_IS_EMPTY in Core and I don't mind where I obtain them from.

TypeTraits is a low level library so it's in principle no problem to allow its use in Core. But I wonder if that (the desire to use it in Core) is not an indication of the functionality in question not belonging in Core. Unfocused libraries like "Utility", "Detail", "Core", if left unchecked, tend to attract all kinds of things and grow beyond any reasonable size. And the fact that we artificially restrict what Core components can use serves as a check. Ideally, we shouldn't need such omnibus components at all.
