Instead of EitherT, the next version will deprecate ErrorT in favour of a transformer ExceptT with base monad Except. The idea is to have analogous transformers and monads
ExceptT : Except : Either WriterT : Writer : (,) ReaderT : Reader : (->)
Great! When do you plan to make a release?
Pre-release docs are here:
http://code.haskell.org/~ross/transformers/dist/doc/html/transformers/
The docs for Control.Monad.Trans.Writer.Strict say:
Although the output is built strictly, it is not possible to achieve linear space behaviour with this transformer: for that, use Control.Monad.Trans.State.Strict instead.
I think it should be "constant", not "linear". Roman
