You can't do this with the current macro package. But as you probably
understand it based more on C-macros than lisp macros. It also allows you
some cool things which lisp macros can't do, for example expand patterns and
insert values anywhere.
You would probably actually need something which is a combination of both.
If you were doing it in Erlang syntax something with a parse transform would
do the trick. But working on Erlang syntax code is messy.
They are actually a terrible hack. :-)
