Data.Map is a standardized interface, *not* a standardized implementation. I'm not saying it's a *good* standardized interface, but it's the only one we've got.

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.

True, it's not entirely stable, but I'd say that it's still more stable than the average external library. It's at least got a community-involved process for review of API changes. -- David Roundy Department of Physics Oregon State University
