FastMutableIntMap will probably be slower than just IntMap

It's just a newtype around IORef (IntMap a). The IntMap isn't mutable. Just the IORef. This just adds GC overhead for no good reason. The only way I can see that this makes sense is if there are plans to change the internals of the module some time in the future?
