Lumars
Lumars is a high-level wrapper around the Lua API. It only targets Lua 5.1 because of LuaJit. It bundles a precompiled version of LuaJit for Windows and Posix x86_64 machines to make it easier to include.
The main highlight of the latest release is the ability to create EmmyLua-annotated code, allowing you to automatically generate up-to-date documentation for your D-side functions, that lua plugins can digest to allow for intelisense. (it has a long way to go still, but this is at least a start for it).

Lumarsh
You could describe it as a "single-binary, batteries-included Lua distro" that aims to provide a decent built-in library for Lua scripts to consume. Personally, I dislike bash, and I like Lua, so I want to use Lua wherever possible >:3
Lumarsh also has support for luarocks, so you can still use external libraries if needed.
Because it's powered by Lumars, it was very easy to expose some select Phobos modules for Lua to use.
dub run lumarsh -- args
is the easiest way to mess around with it.
I haven't actually written the code to generate the EmmyLua stuff yet, but that's because I'm amazingly lazy at times (it should only take 5 mins at most).

They're both still pretty rough around the edges, and definitely have some usability issues, but I feel they're both ready for others to experiment with at least.
