I'd like to use MPL to remove elements of a set from another set.
Try this:

#include 
#include 
#include 
#include 
#include 
#include 

using boost::mpl::set;

struct a {};
struct b {};
struct c {};

typedef set  input;
typedef set     remove_these;

struct set_inserter {
    typedef set<> state;
    typedef boost::mpl::insert operation;
};

typedef boost::mpl::remove_if, set_inserter>::type  result;

BOOST_MPL_ASSERT((boost::mpl::equal));

int main() {
}
