From a first glance, this is the second somewhat opinionated, compact, minimal-dependency interpreter/shell/library bundle despite the Lua(JIT) ecosystem being tiny. The other example I have in mind for this would've been luapower, which sadly became somewhat inactive.

I really like the simplicity of the language and the speed and compactness of its implementation. The JIT is also the real deal, with millisecond cold start execution delays unlike Julia, which masquerades as a JIT/interpreted language while featuring dog slow (by comparison) LLVM ("pre-")compilation under the hood (core language, type system, package management and interoperability concepts are admittedly nice in Julia though).

As another comment suggested, Lua seems to lend itself to certain kinds of projects. This looks like it could mesh well with my forever project to rewrite userland in Love2d!
