Is this a joke?
Sorry for my lack of humor.

3MB executable that does nothing... the horror...

1.6MB here. What compiler did you use? I've got clang with nuwen MinGW has the backend.

You forgot to #include <ciso646>, which is actually necessary on some compilers (notably MS's) to use operator synonyms.

Fixed.

In C++, reserved words exist with the same names as these macros and are treated as aliases of their respective operator. Therefore the inclusion of this header has no effect in C++, and is not necessary in order to use the alternative names.

Now change it back!

It may still be required in order to have the alternative operator representations in old or non-conformant compilers.

Like MSVC.

Now, this is how to not write the hello world program:

#include <iostream>

int main()
<%
	std::cout << "Hello, World!" << std::endl;
??>

How about:

#include <iostream>
 
int main()
{
    std::endl(operator<<(std::cout, "Hello, World!"));
}

I know about ADL, unlike Stroustrup ;)
