Hi James, You're right, Hash does indeed rely on underlying JavaScript vanilla objects, which can only use strings as keys.
Supporting using objects as keys would be a complete rewrite, and a fairly inefficient one in terms of runtime performance (I did it once, and abandoned it as not worthwhile). I'm not aware of any plans to do so. I suspect you'd be better off (from a performance standpoint) building toString / fromString support into your keys. FWIW, -- T.J.
