Actually, instance variables in a "def self.*" method still refer to
the singleton object. The body of that method is treated just like a
method in "class << self". You just don't get a chance, as you say,
to make accessors with "attr_*", since that goes outside your method
definitions.

That's one of the things that attracted me to using class << self to
contain all these methods - it just seemed easier to me to visualise
what was going on.
I'd be really interested to know the nature of the criticisms made
about it in the Matz book Mark mentioned.
cheers
