Comment :  
Generalizes clr\_member to support calls to an explicit implementation  
of an interface method as well as a base class method hidden by a “new  
slot” method.

1. interfaces

public interface I {  
int Foo();  
}

public interface J {  
int Foo();  
}

class C : I, J {  
int I.Foo() { return 1; }  
int J.Foo() { return 2; }  
}

C.new.foo # =\> undefined method `foo’  
C.new.clr\_member(I, :foo).call # =\> 1  
C.new.clr\_member(J, :foo).call # =\> 2

1. new slot methods

c = C.new  
p c.foo # =\> 2  
p c.clr\_member(B, :foo).call # =\> 1
