I assume you mean for the comparator, not storing a set of functors.

I've often used Boost.Function for this, though I'm interested in
approaches that don't involve the function-pointer-like overhead:
typedef Some_Type SetElementType;
typedef boost::function< bool (const SetElementType&
, const SetElementType&) >
typedef std::set< SetElementType, SetElementComparator > SetType;
