I realized what I wrote about amap earlier was utterly boneheaded, because it has the wrong type for fmap. The only way to accomplish my goal is to make Data.Array.IArray.amap a method of the IArray class. This will allow IArray instances to offer optimized versions and things like amap/coerce rules. The current implementation of amap can become the default one.
