Comments? :)

While we can unify Data.Map and Data.IntMap using associated data types (ATs) but I'm not sure if that unification alone is worth a new library in my opinion. My biggest problem with ATs is that they don't scale well enough to support e.g. unboxing of keys and values for every data type. See

In my opinion we need to address the issues I raised in that email before we can create a practical containers library using ATs.

Cheers,
Johan
