synopsis: Derive instances for monad transformer stacks
description:
  Implementing instances for monad transformer stacks can be tedious.
  <https://hackage.haskell.org/package/mtl 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.
