Description
I propose to be able to use thread::id as key type of unordered associative container, add hash_value free function under boost namespace.
Simple implementation is here.
// Should include boost/functional/hash.hpp
// and declare as friend of thread::id.
std::size_t
hash_value(const thread::id &v)
{
return hash_value(v.thread_data.get());
}

Replying to viboes:
Duplicated #6272 c++11 compliance: Add thread::id hash specialization
Does #6272 include supporting Functional/Hash's one? Not only to support std::hash ?
