Oh, I think I missed your point, that this operation really belongs in a *different* class—sorry.

amap :: (IArray a e', IArray a e, Ix i) => (e' -> e) -> a i e' -> a i e

this looks like map. just with a class constraint. I dont buy that theres any ROI for putting it into the class at all.

By the same arguement, map and fold in Vector should be part of the class.

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.
