I would say that the usual approach would be to reimplement the macro
in Python.  The Python Value API is reasonably robust and can usually
be used for this.  If you post the macro definition maybe I could help
with that.  More details wouldn't hurt, either... are you writing a
pretty-printer?  A new command?  A convenience function?
