For next compiler release
^^^^^^^^^^^^^^^^^^^^^^^^^
replace checks against multiple types with .oneOf(...)
replace checks of InferredType against multiple types with .oneOf(...)
replace certain uses of inferredType.getOr(UNKNOWN) by i.getOrElse({ errorhandler })
replace registerOrPair in setOf(..) by .oneOf(..) varargs function
