-- This is a small example for structuring Haskell programs so that
-- you neither have to 1) define half your program to live in IO or
-- 2) build complex Monad transformer stacks where you have to lift
-- several times to be able to do the correct operations.
-- Instead, this approach (shown to me by @am_i_tom at BusConf 2018)
-- uses type classes that define a set of operations and then define
-- a type `App a` that is a small Monad transformer stack of EitherT,
-- ReaderT and IO that implement these type classes. This allows
-- you to write functions that declare (via these type classes) which
-- capabilities they need to run. You can also easily write a different
