For what it's worth, the Edison packages provide such interfaces for many
structures. You might want to ask about experiences.

Hello devs,
I would appreciate feedback on the idea in https://gitlab.haskell.org/ghc/ghc/merge_requests/934
Maps/Sets in GHC for the most part offer the same basic functionality but their interfaces differ. In order to make this easier to work with I propose using overloading via IsSet/IsMap classes.
The goal is to make working with these data structures simpler by having a uniform interface when it comes to names and argument orders.
There are downsides, but to me they seem minor. Error messages can be more confusing when one get's the types wrong. We have to import the class to use it and the like. However overall I think making code easier by not having to remember the naming scheme + argument order for the different possible instances would make this worthwhile.
But GHC isn't my project but one of the community so please voice your opinion on the matter on the merge request!
