Halo was written with a Lisp dialect called blamscript (2014) (opencarnage.net)
I cant help but think that a lualisp merge would be the ideal script addition for all most any engine.
Have you seen Fennel? https://fennel-lang.org
Fennel is a programming language that brings together the speed, simplicity, and reach of Lua with the flexibility of a lisp syntax and macro system.
Full Lua compatibilty: Easily call any Lua function or library from Fennel and vice-versa.
Zero overhead: Compiled code should be just as or more efficient than hand-written Lua.
Compile-time macros: Ship compiled code with no runtime dependency on Fennel.
Embeddable: Fennel is a one-file library as well as an executable. Embed it in other programs to support runtime extensibility and interactive development.
Anywhere you can run Lua code, you can run Fennel code.

Lapis – A web framework for Lua or Moonscript (leafo.net)
Hey, I'm Leaf and I made lapis. Thanks for sharing this
Although a new version hasn't been deployed in a while it's still heavily used (and developed, but it's been mostly stable for me). My current main thing is https://itch.io, which is powered by lapis. I have a bunch of other sites running on it too: https://streak.club https://sightreading.training and I also made https://luarocks.org
itch.io is the largest thing I've ever started, it's currently about 220k lines of MoonScript code.
Feel free to ask any questions!
Marco from Kong here. At Kong we use Lapis for our control plane API and it's been phenomenal so far. If you have a project in Lua and are considering a web framework, I would definitely recommend Lapis - it's mature enough and battle tested. Pro tip: run on top of LuaJIT for extra performance.

Another HN comment:
Man, Moonscript looks amazing, reminiscent of pug/Jade.
Anyone experienced Moonscript? How is it, how is the ecosystem, is it fun?
Ecosystem wise, it's the Lua ecosystem. Compatible, from both sides of the coin.
It's classes are fantastic when working with structures that lean that way, like in games. (I've used it a fair bit with Love2d.)
Comprehensions and stabby-procs are also something that are nice to have. Makes it easier in some cases. Just more consistent in others.
I've used it a bit with love2d for game prototypes. I love it. It has my favorite syntax of probably any language. The community/ecosystem is certainly lacking but growing all the time.
It still needs a bit of work to simplify debugging with some kind of sourcemap functionality. And it is extremely fun, especially in combination with love2d.
That is awesome. I used to write some moonscript for love2d too. Abandoned it for Godot but that really helped me get a better handle on game dev.
CloudFlare uses OpenResty a lot (and is now its main sponsor).
I'be built a DDOS protection reverse proxy using it a few years back. It's still in use and serves thousand of domains with quite a bit a traffic.
The thing about OpenResty is that you can do most of it on your own without a framework at all. If you don't need all the (it's not really that much) stuff Lapis comes with, you could just require the modules you do need with Luarocks or OPM in a route and handle things that way. It's just Lua. If you don't want to use Lapis's ORM though, you could just not do it though. AND Lapis in vanilla Lua isn't especially OO, it looks a lot like Express/Sinatra.

"Goodbye, Lua (2016)"
Yeah, I tend to use Lua exactly for this reason: to escape the dependency hell of JS and Node and so on. Having fewer 3rd-party libraries to use in formulating an addiction to dependencies is often a positive thing.
"In Defense of YAML (atomist.com)"
Helm 3 introducing lua, for example, is a big step forward. Pretty much exactly what I've been envisioning for making k8s deployments less crummy, so I hope they end up with a good product.
