Your right it is, and that should suffice, though I recall matz once talking about the possibility of Module not being a subclass of Class in Ruby 2. Just the same, perhaps we can simplify it to just #enclosure ? ---

But a class is a module, right? Although more exactly one could argue that an instance of a class is a module. Well for me that was good enough an approximation. As a side note I never use class\_eval, but always module\_eval. However if some do not see a class as a (kind of a) module the name would be chosen badly indeed. Cheers R.
