[Boost-users] mpl: remove types from set

Hi!

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

using boost::mpl::set;
struct a {};
struct b {};
struct c {};
typedef set<a, b, c>  input;
typedef set<b, c>     remove_these;

typedef boost::mpl::remove<input, remove_these>::type  result;

And result should be equal(?) to set<a>.
Any idea how to do this?

I'm a newbie on MPL terrain and it is quite brain-twisting... (I could use a beer to relief some strain)

TIA

Alfred
