This would be lovely, and make us as cool as nginx.
Problems to address include conflicts with mod_macro, mod_rewrite, and any
third-party module which might do variable fu.
Having the interpolation ignore stuff starting with Rewrite* or in a mod_macro
definition seems simple enough. Having a generic way for a third-party module
to say "don't interpolate me, man!" could be handy too.
