I was under the impression that the vector<3, free_quantity> syntax was just one alternative to the lengthier one,
That was my understanding too. I see no reason to preclude the type parameter from being free_quantity, and this would automatically allow mixed vectors - and automatically ensure they're only used in ways that make sense.
I have read you whole post, and I totally agree (it was an interesting example too!). I think there was a misunderstanding. The problem is about underlying data type. Do we allow one field of a vector<3> to be double, another field to be int, and another field to be Boost.Rational ?
