This is 'Ludi' an experimental programming language.It is focused on arrays, and has a number of basic features that you can play around with in the interpreter.
> let x = [4 3 2];
> let y = 5;
> print(x*y)
20 15 10
> let z = reshape(iota(8), [2 2 2])
> print(z)
1 2
3 4
5 6
7 8
With a standard Rust toolchain it can be built and run:
cargo run -p interpreter
