Camera.set() and Camera.new() -

[MartinRinehart]

The API doc for Camera.set() isn't right.

Camera.set(), as the name implies, sets the camera. It might have been better to call it Camera.set!(). It does not return a reference to a new Camera object.

Camera.new() returns a reference to a new Camera object and should not be deprecated.

c = cam.set( ... )
c == cam # true

The code example camera = camera.set ... is bad practice. The camera = part should be discarded.

Anyone with a copy of my Chapter 16 and its associated code should get a new copy.
