deriving-trans: Derive instances for monad transformer stacks
Implementing instances for monad transformer stacks can be tedious. mtl defines each instance for each transfomer, but this can be avoided.
Elevator let's you access instances of the underlying monad of a transformer.
Composing transformers with ComposeT brings instances into scope during the
initialization of a transformer stack.
Elevator can be used with DerivingVia to select a specific transformer to
derive instances for a transformer stack.
ComposeT composes transformers and accumulates instances in a transformer
stack.
