I'm a core contributor on the Fennel programming language: https://fennel-lang.org/

It's a young language, but I would love to see it covered by cloc if possible. Luckily it is very simple:

• unambiguous file extension: .fnl
• simple definition of what constitutes a comment: ; marks the rest of the line as a comment

Here are some samples of Fennel code:

• https://github.com/bakpakin/Fennel/blob/master/fennelview.fnl
• https://p.hagelb.org/play.fnl.html
• https://code.technomancy.us/technomancy/trurl/src/branch/master/trurl.fnl
