I think it's a good idea. A boost::hash is basic building block that
every class can use (to be inserted in a hash map), so I think it's
better to isolate it with minimum dependencies in its own module. Hash
Core module sounds good but does this mean that we will add new headers
on boost/hash_core/hash.hpp/hash_fwd.hpp/extensions.hpp and old
functional headers will be redirected to those? I think this is a good
idea to minimize dependencies on functional as some of my libraries only
use boost::hash.
