Hi,
do you think it is worth considering a ratio generator that will ensure a normalized ratio. In thi way
ratio_normalizer<1,3>::type will be the same as ratio_normalizer<3,9>::type. So no need to add the copy constructors and assignement operators.
If we want to do this, I suspect the easiest thing would be to make type a nested typedef of ratio itself:
ratio<3,9>::type is ratio<1,3>
Yes, this looks simple and avoid the normaliZer linguistic issue :).

Best,
Vicente
