Just a side note: you seem to be saying that the define-macro! form is more
powerful than extend-syntax and with. This is not true. Extend-syntax can be
used to do 3-d programming (the technique you describe in your message), and
any macro. It is completely general.
p.s. Extend-syntax was created by Eugene Kohlbecker.
