Nice.
Just a stake, I think
((lambda (x) (x x)) (lambda (x) (x x)))
could be done with backquotes in Common Lisp or maybe Elisp.
Or something like that.
Don't trust me.
@vnikolov I'm sure someone explained it to me before, but while it's trivial to write a macro that creates a quine:
CL-USER> (macrolet ((double (&body body) `'(,@body ,@body))) (double double))
(DOUBLE DOUBLE)
The problem is, I can't get that macrolet inside of the macrolet output without going via a string or something because of how commas (unquotes) work.
P.S.
A tad of cheating:
(defmacro q (&whole f) "A \"macroexpand-1 quine\"." f)
and I can't say if this gives any useful food for `macrolet' thought.
