Support for rST files and PEP257

Hi,
I wonder if anyone has considered support for rST files (I'm thinking particularly of the directives and labels often used when writing for Sphinx?
If I wanted to implement that, do you have any suggestions of the approach I should take?

Thanks!

No file or test is named. Start by examining MagicPython's existing Python syntax-highlighting definitions and how file types are registered across Sublime Text, Atom, and Visual Studio Code. Define the required rST directives, labels, and PEP257 handling before determining what complete support would mean.
