[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 input; typedef set remove_these; typedef boost::mpl::remove::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 -- Desperate Housewives - das Spiel!
