Slight problem: When we do Modules(QQ), then it returns VectorSpaces(QQ). This is why a type checking in ClasscallMetaclass.__call__ would currently crash at startup of Sage. It might be possible to fix it by making VectorSpaces a sub-class of Modules. But I don't know if it would be worth doing. Opinions?
