The compatibility layer could continue to export the old separate types for State, Writer, etc, couldn't it?
It could, though then they'd be different types than the transformer versions. There's a trade-off.
Yeah. I guess we could see how much stuff breaks first. It'll only be the things that rely on it being a real type *and* don't have an upper bound on their mtl deps.
Are there any problems with adding transformers and monads-fd to extralibs pending the Haskell Platform being ready?
That should work, but that wouldn't be till September/October. I'm not sure what the HP schedule is. Another possibility is to upload mtl-2.0 as a compatibility layer.
I don't really understand the relationship between extralibs and hackage - I was assuming that changes to mtl had to go into extralibs to become official. Uploading to hackage as well would obviously help the migration happen sooner.
