Ok, so I have some trouble counting. *grin* Substitute "three arguments"
with "four arguments". My draft message message originally used only x,
radius and color. When I added in the y coordinate, I forgot to
compensate. My apologies!
One other thing to note: this structuring really doesn't have much to do
with OOP. It's more fundamental than that! Many languages have some
mechanism for defining a way to build compound data. C has structs and
Pascal has records. It just turns out that most OOP-ish languages provide
one main construct for bundling data in classes.
