I think there weirdness is because equality and comparison are mixed. Equality can be defined for almost every object, but comaprison makes sense for much smaller set of objects. So I wonder maybe a good solution would be to somehow separate the two. And then maybe raise an exception when trying to compare objects that can't be compared? -- Stas Malyshev smalyshev@gmail.com
