I have a templated class

template class S { //... implementations };

and some stock type implementations for type U, V and W:

typedef boost::mpl::vector u_types; typedef boost::mpl::vector u_types; typedef boost::mpl::vector w_types;

I want to test class S with all possible combinations of the template arguments,

typedef boost::mpl::vector< S, S, // ... S, > s_types;

like this: boost::mpl::for_each(test_func).

The only problem is there are 2*5*5 = 50 combinations that I do not wish to type in one by one.

Is there a way to generate all the combinations with boost::mpl or Boost.Preprocessor?
