Well, when you change the color of a morph using say an inspector to send
it a color: message with a new Color instance, you are in essence ripping
code away ( the old Color instance ) and installing new code on a running
system.
Now, with SmallTalks flexible execution environment, and the myriad
options for inspection, etc, it becomes possible to handle even more
complicated cases.
