I'm not sure what criteria you'd like to use!

PatternSynonyms, PartialTypeSignatures, and NamedWildCards are all pretty stable and should go in.

StaticPointers will definitely continue to be there in future; but the details of the API may change, and the current implementation is very much a prototype.

DeriveAnyClass: I defer to Pedro
