I'm still in favor of adding `EitherT` to `transformers` in addition to `ErrorT`. The only person who disagreed the last discussion was Ross, so it's a matter of convincing him.
I also prefer Ross' suggestion of Except/ExceptT. Using Either as a monad for me is abuse, as is defining Monad for pairs, Num for functions, Ord for complex numbers etc.
I find Henning Thielemann and Ross Paterson's arguments very convicing too.
