Ok, how about this:
transformers H98 bits, registered hidden by default mtl 2 re-exports transformers, adds type function stuff mtl-fd alternative that uses FDs, hidden by default
Are you saying that mtl-2 would be the equivalent of transformers + monads-tf? That might not be a good call; monads-fd is probably more popular than monads-tf.
Yes mtl-2 would be transformers + monads-${the-right-one} Though more precisely, it'd re-export transformers and contain monads-${the-right-one}. I'm not really saying whether it should be the tf or fd version. I've not been taking part in that discussion. But other people have been discussing it and whichever one it is that they agree is the right default, that one should be labelled as mtl version 2. Also, I should say that it would be wrong to push the choice of FDs/TFs onto everyone. We should just pick one. Some people know the difference and can select an alternative. Everyone else just wants to use the same one as everyone else is using. Duncan
