When I typed this in I was surprised to find that the print() happens
without having created an instance of this class yet.  Further
experimentation seems to indicate that all class methods and
attributes get executed and assigned when the class definition is
first read into the interpreter without any need to create an instance
of the class.  This is good to know!

I had actually bookmarked this last week in my browser for later
reading.  I just got finished reading it.  It has brought additional
clarity, but also much more I need to think about and explore.

Thanks, Zach!
