I was thinking of Java & Lua.

Seriously, though. Has anybody done a similar information density study on programming languages?

Isn't that one of the arguments in favour of Lisp and similar languages? That the information density is so much more conducive to writing expressive code that is still sufficiently concise to keep in your head whilst writing it?

It's pretty easy. Just count the characters, or lines. You can play a game to make the shortest code, golf.
