class Bar:
	pass

interface IFoo:
	def Bar(ref x as Bar) as bool

class Foo (IFoo):
	def Bar(ref x as Bar) as bool:
		return true

x as Bar
Foo().Bar(x)   #BCE0004: Ambiguous reference 'Bar': Foo.Bar(Bar), Foo.Bar(Bar), Foo.Bar(Bar).

If parameter 'x' is an external type instead of an internal type, it works.

Simpler testcase (no need for an abstract class in the middle to trigger the bug)
