TypeError: Hash is not a module
        from (irb):1

but "class Hash" works.

I think the OP was asking whether this approach--using the Hash
namespace--which seems more elegant, might have some drawbacks. It might
set you up for some conflicts with constants other code defines in the
Hash namespace.
