Do you realy need to use the variable directly?
My scripts tend to have very little use of '@'.

module Foo
 def bar(key)
   @myvar ||= Hash.new {|k,v| k[v] = []}
   @myvar[key]
 end
end

class Test
  include Foo
end

t = Test.new
t.bar('baz') << 'eeek'
p t.bar('baz')


I didn't followed the whole thread so please ignore me
if this was suggested before.

cheers
