This is based on the assumption that a module equals a class. I don't
think modules were necessarily meant to be used in that way.
Personally, I tend to view the module name as something like a
namespace. The namespace may contain just functions or entire classes,
depending on the design style for that particular project. But a
namespace containing functions (i.e. a module exposing functions) does
not necessarily equal a class, in my view. Hope I'm making sense.
