The attached code isn't conforming, and I'm not seeing a motivation to support
it as an extension.  Here is the conforming way to specialize std::hash:

namespace std {
  template<>
  struct hash<operand::datatype>
  {
    std::size_t operator()(operand::datatype t) const
    {
       return (size_t)t;
    }
  };
}

Reference:  [unord.hash]/p1.  There is no definition of the primary template
hash.

Resolving as "not a bug".
