Been there, done that -- this whole discussion started because the most
recent Rcpp release had accidentally borked Luke's use of assert (as we
didn't prevent the newly added and hany 'tinyformat' one-header-library from
re-defining assert).  (And Kevin also added some other push/pop logic to only
define some other macros when we need them and to generally avoid spillage.)

So now that this has been taken care of, we are discussing how to provide a
more useful feature "not unlike assert" with proper Rcpp semantics.
