Well, yeah, but I was trying to present the common/general case, so as
not to overwhelm Don with tricks he doesn't need yet.

So, Don, if you're still reading:

When you do:

module Foo
   ...
end

or

class Bar
   ...
end

the Foo and Bar parts are supposed to be constants.  (I think Ruby
will even complain if they aren't.)  As Robert points out, there are
other ways to access modules and classes and other such things that
usually have constants for names when defined in the usual way... but
those are stories for another day.  :-)
