I really hope this gains traction. i use Lua in a professional setting on an smaller embedded Linux system. Lua's memory requirements, ability to bind with C, and developer speed really works well for this project.

But it feels like a strain on the Lua community to have LuaJIT essentially "stuck" with Lua 5.1. Many projects seem to have taken a long time to move on and start moving forward to 5.2, or 5.3 which were released in 2011 and 2015 respectively. LuaJIT is so impressive it feels unfortunate to leave that community behind and move forward.

When we evaluated Lua, and which Lua version to go forward to this was our key points:

1. LuaJIT was abour twice as fast for us. 2. LuaJIT has nice C integration/binding. 3. LuaJIT was no longer maintained/developed/etc and was now ~10 years out of date wrt to the core language. 4. Lua is being used in non-performant areas, we have C when we need performance. 5. Integers and bitwise from 5.3 operations are important for us. 6. Overall the changes in 5.2 and 5.3 are good language improvements.

We ended up going with Lua 5.3 due to ongoing development, and for us it ticked all the boxes. But it would amazing to have the options to use LuaJIT, and to encourage everyone to move forward instead of being stuck on 5.1.
