| Great, thanks!  Do you meanwhile have a non-release hotfix which also no
| longer uses R_NamespaceRegistry?

I made the two-line check of conditioning on 4.6.0, not 4.5.0, and dropping
it in. The sole segment where it appears is now changed to

        Function_Impl(const std::string& name, const std::string& ns) {
#if R_VERSION < R_Version(4,6,0)
            Shield<SEXP> env(Rf_findVarInFrame(R_NamespaceRegistry, Rf_install(ns.c_str())));
            if (env == R_UnboundValue)
                stop("there is no namespace called \"%s\"", ns);
#else
            Shield<SEXP> env(R_getRegisteredNamespace(ns.c_str()));
            if (env == R_NilValue)
                stop("there is no namespace called \"%s\"", ns);
#endif
            get_function(name, env);
        }

Tests ok with R-release and R-devel. As we haven't released this non-release,
I kept it at 1.1.1-1. New files in the same location
