This is a bad idea. A set doesn't pay it's weight for small numbers of items. 
In the vast majority of cases, it's faster to use a sorted vector/qlist 
instread of a set. A set is node-based, while a (q)list is simply an array. 
Locality of reference and malloc-free appends ruin set's day.

Thanks,
Marc
