Could `Rcpp::stop()` get `include_call = true` as an argument?

[DavisVaughan]

I see how Rcpp::stop() works here

Rcpp/inst/include/Rcpp/exceptions/cpp98/exceptions.h

Line 126 in f3c5a34

inline void NORET stop(const char* fmt, const T1& arg1) {

Would it be possible to add bool include_call = true to the end of each template implementation and pass that on to Rcpp::exception()? Would that be a non-invasive change?

I see I could set RCPP_DEFAULT_INCLUDE_CALL but I don't think I love that idea.

Rcpp/inst/include/Rcpp/exceptions.h

Line 37 in 2f72ff8

explicit exception(const char* message_, bool include_call = RCPP_DEFAULT_INCLUDE_CALL) : // #nocov start

I could also make my own stop() on top of Rcpp::exception() but I'd hate to have to copy/paste all that boilerplate from Rcpp::stop(), and appreciate that it already formats string input for me.

@DavisVaughan I don't think that's possible due to how we are obtaining the parameters. The best option would be setting the RCPP_DEFAULT_INCLUDE_CALL define.

It's also "fairly recent" code from #868, maybe start by reviewing that discussion?

[DavisVaughan]

Gotcha, I see now how that won't work especially with the cpp11 variadic template argument

Rcpp/inst/include/Rcpp/exceptions/cpp11/exceptions.h

Line 51 in f3c5a34

inline void NORET stop(const char* fmt, Args&&... args) {
