I'm a little confused at where you're coming from. Do you program microcontrollers or something? Since when has recursion or the ability to allocate memory been an issue? 30 years ago, maybe? I understand lisp isn't trivial to implement if all you have is assembly with no OS or libraries, but beyond that it's pretty damn easy. Even in C it only takes a few dozen lines. > Javascript I'm not a JS programmer, but I think JS has had infinite lexical scope at function-level since the beginning. It does not have scope at block-level, which is the confusing part.
