Two classes, one in each module. Foo.Foo and __main__.Foo

When you run a script, it executes the code in the context of the module 
called __main__. When you import a module it has a separate context even if 
the script and the module came out of the same source file. Importing a 
module executes each line in the file, even if you already ran most of them 
as a script.

Every time you execute a class statement, even if the class name is the 
same, you create a new class.
