During some code refactoring I discovered this is compiling without
errors or warnings. I guess this is another nice entry for obfuscated
C++ quizzes...

#include <iostream>
#include <string>

int foo() {
return 321;
}

int main() {
std::string name;
name = foo();
std::cout << name << std::endl;
}

Maybe I'd got it if I'd be warned with a narrowing warning because
of narrowing from int to chat.

This warning is not activated by common warning settings like -Wall
-Wextra, or /W3, so needs to be switched on first (and then one must
clean up the codebase to get rid of the myriad of false alarms).

For reference, the narrowing warning is called -Wconversion in gcc and
C4242 in MSVC (`#pragma warning(default: 4242)`).
