That's Scheme.  Lexical scope adds complexity, which is why it appeared
relatively late in Lisp history.  Anyway, it's just 32 LOC.  And that
includes a bunch of stuff like QUOTE and IF etc. in the evaluator
(basically everything that expects unevaluated args), that in most
implementations would be done as macros.  The evaluator would then need
macro expansion, but that's just a couple more lines to replace a dozen
or so that get eliminated.

Shrug, people use Emacs Lisp all day long.  I'd say that counts as a
real thing.
