But I Miss My C++ Iostream

Sometimes there's just no accounting for taste...However, just as you can append an object to an Array using the << operator, you can also append an object to an output IO stream:

endl = "\n"
$stdout << 99 << " red balloons" << endl
99 red balloons

Again, the << method uses to_s to convert its arguments to strings before sending them on their merry way.
