The question is, what classes do that module systems don't? Modules (at least in Python) are singletons.

  Doesn't count. When you define a single data structure in a module, (along with functions to manipulate it) you can instantiate it just like you would a class.

    Ugh. That's like saying that high-level programming languages "don't count" because you can do that stuff in assembler.

      I'm not arguing Turing completeness here. I'm arguing trivial one to one mapping. Syntax sugar. Compare: struct foo { int bar; float baz; }; int get_bar(foo); float get_baz(foo); Which would emulate this: class foo { public: int get_bar(); float get_baz(); private: int bar; float baz; }; If you're interested, I wrote more about that here: http://loup-vaillant.fr/articles/classes-as-syntactic-sugar http://loup-vaillant.fr/articles/classes-as-syntactic-sugar
