What about ErrorT monad transformer?
I don't see how it helps in my situation. ErrorT doesn't catch exceptions, for example. Suppose I did make something like ErrorT that catches exceptions and turn them into Lefts. Where would (>>=) get my specific error constructor? Maybe I need to make helper functions to use in runErrorT blocks that turn exceptions, Bools, Maybes, etc., into Eithers? Confused.
