      << (Ninary Left Shift, Output to Stream Through Call to Write(out_stream) Method)

      The binary left shift operator:

      • Looks for a write() method in the first operand. If this method exists, invokes it with a single parameter that is the second operand.
      • Otherwise assigns the first operand to a newly created temporary value, executes the left shift equality with this value and the second operand so that the result is a return value of the expression.
      • Throws an exception otherwise.
