Here’s an example of why we like c-style operators, i.e. it reduces redundancy of the variable name. It’s no surprise that programmesr figured out "viewTransform := viewTransform  *” could be compressed and still have the same meaning.

  viewTransform := TMat4.Identity;
  viewTransform *= TMat4.Translate(x, y, 1);
  viewTransform *= TMat4.Scale(scale, scale, 1);

	or

  viewTransform := TMat4.Identity;
  viewTransform := viewTransform  * TMat4.Translate(x, y, 1);
  viewTransform := viewTransform  * TMat4.Scale(scale, scale, 1);
