docs: Return a dict with the Python implementation and version.
  
      Provide both the name and the version of the Python implementation
      currently running. For example, on CPython 2.7.5 it will return
      {'name': 'CPython', 'version': '2.7.5'}.
  
      This function works best on CPython and PyPy: in particular, it probably
      doesn't work for Jython or IronPython. Future investigation should be done
      to work out the correct shape of the code for those platforms.
