You could skip the step of making Foreign.Marshal.Error.void and Control.Monad.void the same function and deprecate Foreign.Marshal.Error.void immediately. However I generally think that explicit or qualified imports are the best way to avoid name clashes. There are many programmers out there that do not program Haskell every day and do not know where 'void' is defined when they read a Haskell program.

Normally I use qualified imports, but these two modules are special. Foreign must be imported unqualified when used with hsc2hs, because hsc2hs emits unqualified identifiers.

I can't remember problems with hsc2hs, but I usually import not the whole Foreign, but Foreign.Storable etc. individually.

And Control.Monad.... well, it doesn't have to be unqualified, but since it's full of control structures it's one of the few modules I'm accustomed to importing unqualified.

I also use to import unqualified from Control.Monad, since identifiers like liftM2 already contain the monadic 'M'. However in this case I import explicitly: import Control.Monad (liftM2)
