Deprecate Error and ErrorList classes #78

Closed chessai closed 4 years ago

The existence of these classes is extremely strange to me. I think now that ListT and ErrorT are being removed, these can be deprecated. What do others think? @haskell/core-libraries-committee

Also, this needs a proper library mailing list proposal

Aren't they removed altogether? https://hub.darcs.net/ross/transformers/patch/7c809b6f9db019ed761c971d10c86fa004f60d89
