Yes, I suppose it's what I want.
Every contract/model has its own header file.
In each, I can extend the map (in the first header, the map will start from
empty.
In subsequent headers, the map will be extended)

The test suite will have a number of translation units to spread the work,
Each would include just some of the headers, building partial maps.

My models have only static functions, there are no instances.

Best,

Does this not work?

typedef mpl::map< mpl::pair<model1,mpl::set<contract1,contract2>,
                   mpl::pair<model2,mpl::set<contract3,contract4> >
    valid_combos_map_t;

That is gonna be a huge map though. It might be easier on your compiler 
for you to move this to a runtime map.
