Indeed.
I actually made the same typo a few days ago but as I recall the compiler was
also pretty clear that I was wrong there and gave me a hint.
Quick check seems to confirm that:
R> library(Rcpp)
R> cppFunction("bool foo() { Rcpp::Rcout << \"abc\" << std:endl; }")
file755d734bf516.cpp: In function ‘bool foo()’:

(As an aside, I really dig how the error messages got better. This is g++
8.2.0 on Ubuntu 18.10.)
