description:
  A Tardis is a combination of both a forwards and a backwards
  state transformer, providing two state values that \"travel\"
  in opposite directions.
  .
  You can install this library with the @use-undecidable-instances@ flag,
  but this feature is only provided for toying around.
  If you depend on this library, or install any libraries that
  depend on this library, then you should install this library /without/
  that flag.
  .
  A detailed description of what a Tardis is and how to use it
  can be found in the documentation for Control.Monad.Tardis.
