Looks like Hydra builds are getting stuck again? Another PR also currently fails its Hydra build but succeeds in other tests. |

All tests pass but Hydra build fails. The same thing is happening in another PR: #2611 I'm not sure what needs to be done; perhaps Hydra is caching a stale failed build? |

This PR adds four new data constructors to
Dhall.TH.HaskellType:SingleConstructorWithandMultipleConstructorsWithare similar to their counterparts without the "With" suffix. They take an addionalGenerateOptionsvalue that is used instead of the global one. They are suitable if you have some weird Dhall types which do not translate to Haskell easily and you don't want to apply the modifiers to all other generated types.Predefined: Use an existing Haskell type for a Dhall type. Suitable if you want to useData.Sequence.Seq SomeTypeinstead of[SomeType]or if you want to translate Dhall maps to Haskell maps.Scoped: Limit the scope of the lookup of other Haskell types used in the translation process. Together withPredefinedthis allows you to use e.g.Data.Sequence.Seqfor some particular types while all the others use the usual Haskell lists. It also allows you to generate two distinct Haskell types that use the same Dhall type as input.
