Actually it's not implemented anywhere by a built-in. The  
__noSuchMethod__ name is accessed only when a method call would  
otherwise fail because of a primitive-type callee. So, the built-in  
is the magic name and attempt to get its value as a "last ditch"  
invocation effort. Note that __noSuchMethod__ works for constructor  
calls too.

Hope this helps,
