Prelude and (:) and ((:), ) bugs?
Mon, 24 Sep 2001 07:31:03 -0700
The Report quite deliberately does not allow you to write
the type constructors for built-in syntax in import or export lists.
The idea is that the types
and  Int
always mean "list of Int" regardless of what module fiddling
you have done. So  is not an ordinary type constructor, to=20
be imported or hidden at will. It always means "list as defined
in the Prelude".
I'll add a paragraph to 4.1.2 to make this explicit.

| As far as I can tell, the report doesn't allow (:) or ((:),=20
