<pre>Try seeing your program as follows (which is what actually happens):
#include <iostream>
int bar() {
std::ostream& os1 = std::cout.operator<<("bar");
std::ostream& os2 = os1.operator<<(std::endl);
return 1;
}
int main() {
std::ostream& os1 = std::cout.operator<<("return: ");
std::ostream& os2 = os1.operator<<(bar());
std::ostream& os3 = os2.operator<<(std::endl);
return 0;
}
then you'll understand why the output first shows "return: ", then the result
of bar().
Note that in my testing, both clang and gcc give exactly the same output. If
your version of gcc prints something different, then that is either a bug in
your gcc, or in libstdc++.</pre>
