It needs a bunch of love. It really needs a way to define new builtins externally, and it needs co-routines. And it needs a way to do binary (my idea: treat binary as an array of small integers, and if you ever insert any other kind of value, then you either get an error or you get an array that's mostly of small integers and no longer "binary" in any way).
