Derive Generic instances #37

Closed Avi-D-coder closed 1 year ago

treeowl commented 1 year ago

This seems very strange to me. Generic instances are for types intended to be used "concretely" (constructors exposed), not ones intended to be used through an abstract datatype API. Generic functions will happily break all the data structure invariants, and there's not really a whole lot you can do with them that's likely to be useful.

If you wanted, you could add hand-written Data.Data.Data instances. We have those in containers and pqueue. Those are a lot more tolerant of restrictions.

No need. I do not remember what I was using this for :)
