hello,
as i don't immediately see an MPL equivalent of multimap, here is what i am trying to achieve.

I have a number of models (200 types, all of them inherit from 1 base class)
and a number of contracts(400 types, also all them inherit from 1 base class),
and I try to write a test suite for valid combinations.
Was there a multimap in MPL, i would have stored this matrix:
model1 contract1, contract17, contract156
model2 contract17
...
model200 contract23

or symetrically, indexed by contract
in a multimap.

Are there solutions with other MPL sequences?

Rds,
