Not so! There is another more venerable interface, namely Data.FiniteMap.
That interface was deleted in favour of Data.Map, for no good reason
that I am aware of. Indeed, I still have several pieces of software
that continue to use the FiniteMap interface, but now have an extra
home-grown indirection layer to connect to the current Data.Map
implementation, just to enable the software to build.
