synopsis: YieldT monad transformer
description: |
  This package defines a class @MonadYield a@ for monads that can emit values
  values of type @a@ while they run, and a monad transformer @YieldT a@ which
  implements this class such that the emitted values can be captured in a
  streaming manner.

  This is an amalgamation of concepts from @pipes@, @conduit@, @foldl@, and
  @kan-extensions@, combined into a small self-contained package.
