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 ?

Please see my direct reply to Michael, titled
"Re: [boost] [PQS] free_quantity contra int,double and Boost.Rational"
