Overview

Forbids declaring a class inside a module declaration. Instead, the class must be declared with the compact namespace syntax, like class Foo::Bar. An empty module module Foo; end, a module that contains only other modules, methods, or constants, and a class nested inside another class are all allowed; only a class whose nearest enclosing scope is a module is rejected.
