What's an example of a "not real language" then? I'm feeling a little hard pressed to find an academic language that is not used in industry. I always thought of Lua as academic because I associated it with Torch, but Facebook and Google are both heavy users of Torch, besides Lua has been heavily used in gaming as an embedded scripting language outside of machine learning applications.
Neovim is also working on replacing VimL with Lua (by translating VimL to Lua). I think that'll be pretty cool (you will be able to match the emacs people on having all of your configuration in a full programming language).
