Hello all,

Can anyone give me a hint on how to call a functor on the differences of two same size mpl::vector types?

For example, given:

typedef boost::mpl::vector<int, char, short, double> v0_type;

typedef boost::mpl::vector<int, int, short, std::string> v1_type;

We can see that the second and third elements don't match, so I wish to call a functor twice, with the following signature:

struct SomeFunctor {

template <typename T, typename U>

void operator()(T t, U u) const {

// do something nice here

}

};

In this example, functor would be called twice: once with [T=char, U=int] and another with [T=short, U=std::string], along with their values.

Thanks for any light,

Rodrigo
