[Template-haskell] Accessing module imports in TH

[Simon Peyton-Jones]

Currently no.  

Asking whether "x" or "M.x" is in scope would be quite easy to
implement, although it doesn't exist at the moment.

Hmm.  Actually I think you could do 
	qRecover (qreify (mkName "M.x"))

to get the effect, couldn't you?  the reify will fail if the name isn't
in scope, but you can catch the failure with the recover.

Asking what is *exported* would be harder.  Ghc doesn't process the
export list until after processing all top-level splices, because the
things to be exported might not be in scope until then.
