See for example fsm.cpp here:

Unfortunately, there is no documentation yet. I hope MPL interface can help
understanding it.
Basically, you turn *definition* defined below into MPL Associative Sequence
with simple typedef overloads::set<definition>. It will behave similar to
mpl::set<int(int,int), float(int,float)>. Note that without typeof deref
can't be defined (workaround exists).

struct definition
{
    int   operator()(id<1> , int a, int   b) const { return a + b; }
    float operator()(id<2> , int a, float b) const { return a + b; }
};
