'isClass' really means "class constructor", which is a special case (gets a prototype property during MakeConstructor (https://tc39.github.io/ecma262/#sec-makeconstructor) during step 16 of ClassDefinitionEvaluation (https://tc39.github.io/ecma262/#sec-runtime-semantics-classdefinitionevaluation).

I'll add some extra tests either tomorrow or during the week)
