regarded and expertly designed C++ library projects in the

boost::hash_value — Implementation of a hash function for built in arrays.
template<typename T, unsigned N> std::size_t hash_value(T (&val)[N] ); template<typename T, unsigned N> std::size_t hash_value(const T (&val)[N] );
Generally shouldn't be called directly by users, instead they should use
boost::hash
, boost::hash_range
or boost::hash_combine
which
call hash_value without namespace qualification so that overloads
for custom types are found via ADL.
Notes: Overloads for other types supplied in other headers.
This is an extension to TR1
hash_range(val, val+N)
