Is there a python/clojure/java version of this?

  Not that I know of. It exploits some of JavaScript's weird scoping rules to keep everything very short. You're not going to get that in most other languages.

    You mean this bit: with (DATA) return eval(value.substring(1)); ? It can be implemented in Python without any problems. Of the dynamic languages I know, at least PERL, Python, Ruby, Smalltalk, Lua, Io, Racket have support for something similar. And even if not directly supported, any other language with `eval` would probably be hackable enough to implement this. In TCL that's actually a common idiom. Anyway, I'm not aware of any JS feature which wouldn't be easily replicated in most other dynamic languages. JS was rather unlucky when it comes to language features - its development stalled for years, while in the same time Python, Perl, Ruby, PHP evolved quickly. JS only now gets features implemented in other langs many years ago.
