So the part I don't get is, why not write the global
operator>(Cstruct,Cstruct), or a plain old functor? I don't see how your
infinitely adjustable set of classes makes the code any easier to read or
maintain. (Or it could be I need another cup of coffee...)

IF C++ had a templated typedef, you could write it as a lambda statement.
typedef lambda_statement<T> CompareOperation;
typedef containerType(C *, CompareOperation);
containerType container(CompareOperation(free1->*(&C::member1) >
But without that typedef, (and some other hand waving) writing the lambda
typedef operation would be grounds for cruel and unusual punishment.
