ROS consists of a collection of tools, libraries, and conventions that aim to simplify the task of creating complex and robust robot behavior across a wide variety of robotic platforms. Summary. This list is to contain discussion of speculative language ideas for Python for possible inclusion into the language. If an idea gains traction it can then be discussed and honed to the point of becoming a solid proposal to put to python-dev as appropriate.
