Yes, I think hiding identifiers is bad style as well. This only comes up because we're too lazy to write out qualified names.

Well, perhaps. But consider

module Some.Very.Long.Module.Name where import Prelude hiding (map) map = ... foo = ...... map ....

Now, do I really want to be forced to write Some.Very.Long.Module.Name.map on the right-hand-side of the defn of foo? There is no easy way currently for me to create a short synonym for the defining module name. e.g.

import Some.Very.Long.Module.Name as Local

I'd prefer such self-imports if they wouldn't need so much effort.

me too. I have requested it on the list before. they should be straightforward to add, the recursive module namespace rules are not very complicated at all and just allowing self-import doesn't involve anything but tweaking the renamer a bit and a fast fixpoint iteration.
