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
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

At least, such a recursive module import would be
possible, but tricky to set up and maintain when the
module changes over time.
