Hello, there is a syntactic form called define-local-member-name [1] that may be used to control the scope in which public methods can be accessed. Arguably, something like the protected scope known from languages like C++ or Java is a Bad Thing (TM) anyway, because there isn't really a fundamental difference between client code of a class that accesses a separate instance and client code of a class that inherits its functionality. Some recently developed object oriented languages (eg. Ceylon) have only public and private scoping for this reason.
