Building with mtl-2.3-rc3 fails:

This is already fixed in #125, but I don't want to release it until mtl-2.3 is actually finalised.

Ah sorry, didn't look through the PRs, only through the issues. Yeah, would be great if we finally knew what the plan for mtl-2.3 is.

I suppose you could release now, and in the unlikely case that it fails to build with the actually released mtl-2.3, restrict back to <2.3 via a revision. (EDIT: I just did so for regex-tdfa.) This would make testing packages with mtl-2.3-rc3 easier.

(Btw, I support your position of releasing mtl-2.3 just to allow tranformers-0.6, and deal with the PVP issues (reexports) later.)
