What are some pragmatic embedded scripting languages of choice these days if one has to consider:

1) Ease of learning, ideally minimal deviant behaviour (eg i consider lua tables to be a new concept in itself)

2) Reasonably fast. Not as much as lua jit but even half would be good enough

3) Mature

4) Has Rust bindings

Lua. Lua tables are easy and awesome. My hobby language unites Lua tables with functions too.
