Hello all,

I have the following:

template<typename T> void f() { /* ... */ }

typedef boost::mpl::vector my_vec;

I'm looking for a way to call f<T>() for all types T in my_vec. I initially hoped that either an mpl algorithm or fusion::for_each might be able to accomplish this for me, but after reading through their docs this doesn't appear to be the case.

struct call_f { template <class Wrapper> void operator()(Wrapper) Sorry, it's missing a "const" right here--^^^^ { f<typename Wrapper::type>(); } };

mpl::for_each >(call_f());
