    "# Control Flow\n",
    "\n",
    "There are three basic types of control flow operation; Branch, Iteration and Jump. The most powerful of the three is Jump. In the early days of programming we used a dark art known as goto to jump from one section of code to another. Programming is more civilized now, instead of goto we use the invocation of a functor for that same behavior. Functions will be covered in the next module.\n",
