I absolutely understand that much.

If I think about this in the context of a property, which in my newbie
mind gives you the ability to 'override' the standard behavior when
getting, setting or I suppose deleting a specific attribute.  I think
I understand what you meant by 'compute the value on the fly', the
keyword being *compute*?
