Example from Rcpp itself, file Environment.h:
Shield<SEXP> res(Rcpp_fast_eval(Rf_lang2(asEnvironmentSym, x), R_GlobalEnv));
For Rcpp_fast_eval, you may still need to #define RCPP_USE_UNWIND_PROTECT
before including Rcpp.h; as I recall we were seeing too many side effects in
other packages when globally enabling it. Or you can play it safe and simply
This really was more of a rcpp-devel question.
