In addition to gah4's excellent list, I would include Lisp in which a
significant fraction is implemented as macros which build on a simpler
version of Lisp. And of course, Lisp's metalanguage is Lisp.


Some amount of Scheme also is macros building on simpler Scheme,
however Scheme's metalanguage is not Scheme but a hybrid that includes
Scheme. How much is implemented using macros depends on the particular
implementation.


YMMV,
George
