[Hat] Hat bug report: import Prelude hiding ...

[Fergus Henderson]

Although Hat does support "import Prelude hiding (head)",
if you substitute other symbols than "head", in at least
some cases it will fail:

	bash$ cat Bug.hs
	import Prelude hiding (sin)

	bash$ hmake -hat Bug
	hat-trans  Bug.hs
	Wrote Hat/Bug.hs
	/usr/bin/haskell-compiler      -c -package hat -o Hat/Bug.o Hat/Bug.hs

	Hat/Bug.hs:8: Module `Hat.Prelude' does not export `asin'

Fortunately there is a reasonably easy work-around for this one:
instead of using "import Prelude hiding ...", you can use "import
qualified Prelude" and then explicitly qualify all Prelude symbols.
