This is where Python shine I belive. Its import system is amazing. We can import the whole file or just particular funcion/method in that file. We can import relative with `.` and `..` and even `...` And we can "import as" to avoid name conflict. Using import together Mock library we can even swap out(Mock) particular imported item during unit test. If one thing I would love to see is having that import system in Python ported to Ruby. Granted that the way Ruby currently works also expose a few functionality for doing DSL easiser.
