I noticed it when I was in there for LUB, so I figured I'd do some
spring cleaning. Changes are:
- Consolidate duplicate code in namedParameterTypes,
normalParameterTypes, and optionalParameterTypes into a shared
_forEachParameterType() method.
- Consolidate duplicate code in isSubtypeOf() and isMoreSpecificThan()
into a shared _testTypeRelation() method that is parameterized over
the specific relation.
- Also some other small-scale changes in the relation code.
