Don't let occasional strokes of brilliance on my part
lead you to believe that I lack the ability to also be
a complete moron.

Gads, I saw and used that, then forgot that, then when
I was seeing the:

  class << anObject
    ...
  end

syntax I forgot I already knew how to do that, tried to
use it, failed miserably, then got confused.

Thanks,
Ben
