Build it and see, I am sure there is.

I built a quick mockup a while back, in LuaJIT based on the Go array
model https://github.com/justincormack/slice

The main thing if you don't use Luajit is finding a way to describe
the types, which is a fair amount of work, while you get this for free
in LuaJIT.
