	 * Some generics notes:
	 * 
	 * Andy 6-May-05 We were having trouble with parameterized types in a couple of places - due to TypeVariableBindings. When we
	 * see a TypeVariableBinding now we default to either the firstBound if it is specified or java.lang.Object. Not sure when/if
	 * this gets us unstuck? It does mean we forget that it is a type variable when going back the other way from the UnresolvedType
	 * and that would seem a bad thing - but I've yet to see the reason we need to remember the type variable. Adrian 10-July-05
	 * When we forget it's a type variable we come unstuck when getting the declared members of a parameterized type - since we
	 * don't know it's a type variable we can't replace it with the type parameter.
