[Python-ideas] Add __main__ for uuid, random and urandom

It's dangerous to talk about a new feature the 1st of April, so I'll start by saying this one is not a joke. I read recently a proposal to allow md5 hashing doing python -m hashlib md5 filename. I think it's a great idea, and that can extend this kind of API to other parts of Python such as: python -m random randint 0 10 => print(random.randin(0, 10)) python -m random urandom 10 => print(os.urandom(10)) python -m uuid uuid4 => print(uuid.uuid4().hex) python -m uuid uuid3 => print(uuid.uuid3().hex)
