Comment (by dons):
This is a generalization of the well-known FFI 'void' function:
{{{
module Foreign.Marshal.Error
-- |Discard the return value of an 'IO' action
--
void :: IO a -> IO ()
void act = act >> return ()
}}}
in base for the last decade. Generalising 'void' (with that name), seems
more intuitive to me.
