I think that's correct, (it at least fits the pattern for 'with'
functions in Haskell).

They're idiomatically used with syntax like this:

> buildReaderFun :: String -> CodeGenModule (Function (IO ()))
> buildReaderFun nm = do
>  puts <- newNamedFunction ExternalLinkage "puts" :: TFunction (Ptr Word8 -> IO Word32)
>  withStringNul nm $ \greetz -> createFunction ExternalLinkage $ do
>          tmp <- getElementPtr greetz (0 :: Word32,(0 :: Word32, ()))
>          call puts  tmp -- Throw away return value.
>          ret ()
