Yes, it does.

We'll have to do something like

#ifndef BOOST_NONCOPYABLE_BASE_TOKEN_DEFINED #define BOOST_NONCOPYABLE_BASE_TOKEN_DEFINED

namespace noncopyable_ {    struct base_token {}; }

#endif

then derive noncopyable from that and repeat the above definition where it's used in Type Traits.

Or maybe have it just in TypeTraits and use it in Core. It could be named appropriately, e.g. noncopyable_base.
