      Note a gosu class can be BOTH parameterzied AND generic. For example,

      class Bar { function blah() : T {...} } class Foo extends Bar {}

      The class Bar here is parameterized by the type var from Foo, yet it is still a generic class. The blah() method in Foo's typeinfo must have a return type consistent with Foo's type var upper bound, CharSequence. //## todo: maybe we don't need this concept any longer? i.e., parameterization should work correctly regardless.

      Parameters:
      typeParams - type parameters
      Returns:
      generic type variables
