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.
