So the way to do that in REBOL is creating a dialect, like the BUILD function. Since REBOL is more dynamic than Lisp (REBOL cannot be compiled, while Lisp is a compilable language), it does not need macros as much as Lisp does; so the need for a dialect like BUILD is not that strong, and that's why it's not built in. It has to be said, that while you would not be able to really do macros in Lisp without having quoting, i.e. without support in the syntax, you can do all that in REBOL without any special support.
