It would need a set in base. I wonder if it was ok to use the Data.Set implementation internally in base, without exposing it.
Ah yes, this is what stopped previous attempts at getting ordNub in. The GHC team is very keen on getting more things *out* of base. Unless something has changed, getting them to include new things in base, even if hidden, would be extremely difficult. Adding additional dependencies and maintenance burdens would add extra work for the overburdened GHC team and slow the GHC release cycle. How about adding a module named something like Data.List.Nub to containers and putting ordNub in there? Or just go back to the idea of putting it in Data.Set. -Yitz
