I'm not sure I understand. This works fine:

(define-macro when (lambda (x y) `(if ,x ,y)))

Yes sorry, that problem was just an artifact of my redefinition of define-macro in chjmodule (I'm redefining it to create both compile-time and runtime macros). I've corrected that bug of mine since (not sure it is in my latest released chjmodule version though).

No, the problem is deeper than that:

(define-macro when (let ((a (lambda (x y) `(if ,x ,y)))) a))
