Just a note on general OO technique; normally, there's no need for a module that defines a class to export any symbols because you want your objects to be encapsulated: the functionality an object makes available to the programs that use it is typically expected to be accessed through an instance of the object, or, in the case of class methods, by explicity referencing the class method through its fully qualified name. If you find yourself wanting to export a lot of functions or other symbols from a module that defines a class, then it might be time to rethink your design.
If not P, what? Q maybe?
