I like this idea, because it would enable non-monadic embedded DSLs to use layout.

For example, consider setting properties in wxHaskell:

layoutSet myButton $$ text := "Ok" on action := doSomething

You can abuse do notation to achieve that, by wrapping the list in a suitable Writer monad layoutSet myButton $ do text &= "Ok" on action &= doSomething with (&=) :: Property a -> a -> Writer Properties () It's ugly semantically but pleasant syntactically.
