Ok I see.
Of course you can achieve this simply via one overloaded function.

bool b1 = question<std::less>(all_of(a),any_of(b) );
bool b2 = question(frobnicates,all_of(a),any_of(b) );

The use of the dummy expression |frobnicates| is a poor substitute for a user
defined operator. Should C++ incorporate a facility to define ones own
