[Python-Dev] PEPs: ``.. code:: python`` or ``::`` (syntaxhighlighting)

I tried using code blocks while writing PEP 551 but they weren’t highlighted on the python.org rendering.

Personally I think it would be great, provided a good colour scheme is available (some default schemes are... not always works of art). I’m not sure who is responsible for that side of things though – presumably it’s just a case of installing pygments. (FWIW, I’m not keen on going back and modifying old PEPs, but I won’t stop someone doing it on their own terms.)

In ReStructuredText, this gets syntax highlighted
because of the code directive [1][2][3]:

.. code:: python

   import this
   def func(*args, **kwargs):

This also gets syntax highlighted as python[3]:

.. code:: python

   import this
   def func(*args, **kwargs):

This does not::

   import this
   def func(*args, **kwargs):

Syntax highlighting in Docutils 0.9+ is powered by Pygments.
If Pygments is not installed, or there is a syntax error,
syntax highlighting is absent.

GitHub does show Pygments syntax highlighting
in .. code:: blocks for .rst and .restructuredtext documents [4]

1. Does the python.org PEP view support .. code:: blocks? [5]
2. Syntax highlighting is an advantage for writers, editors, and readers.
3. Should PEPs use .. code:: blocks to provide this advantage?
