Hrm, oops, I misread your intentions in the original post.

Yes, I find this highly odd and annoying, but I guess it's there for
something useful (even though I'm not sure what that something is ;).

Anyhow, what I've done is use @instance variables for the _class_,
which is like a static variable in other languages, in that it's
unique to the given class but not subclasses.   Accessors to this
are a quick addition if they're necessary.

However, looks like you found what you wanted with the explicit
referencing of constants.
