On the website it says:
If you have written a Pygments plugin that is open source, please inform us about that. There is a high chance that we’ll add it to the Pygments distribution.
Well, I already have a lexer for my own Pure programming language as an addon here: https://github.com/agraef/pygments-lexer-pure. The lexer class is in the pure.py module. Pure is a functional programming language, so it would be most appropriate to add it to functional.py.
It would be nice if it could be added to the core, thanks!
