* Added custom type error messages when Properties don't combine due to
conflicting MetaTypes.
* Added custom type error messages for ensureProperty and tightenTargets.
+ * Note that those changes made ghc 8.0.1 in a few cases unable to infer
+ types when ensureProperty or tightenTargets is used. Adding a type
+ annotation will work around this problem, if you cannot upgrade
+ to a newer ghc that handles them better.
* Use the type-errors library to detect when the type checker gets stuck
unable to reduce type-level operations on MetaTypes, and avoid
displaying massive error messages in such a case.
