[Haskell-cafe] Control.Monad.Error deprecated?

Hello everyone, I just discovered that Control.Monad.Error [1] has recently become deprecated in favor of Control.Monad.Except [2], and I am curious about what motivated the change. Can anyone explain? Thanks, Karl 1: http://hackage.haskell.org/package/mtl-2.2.1/docs/Control-Monad-Error.html 2: http://hackage.haskell.org/package/mtl-2.2.1/docs/Control-Monad-Except.html
