Yep.. Thanks alot. This some pretty neat stuff. :-)

hash = {
     "foo" => Proc.new {
          x = []
          y = []
          hash = {
               "x" => ["a", "b", "c"].each {|i| x << i},
               "y" => ["x", "y", "z"].each {|i| y << i}
          }
     }.call
}
puts hash['foo']["y"][1]
puts hash['foo']["x"][1]

>ruby test1.rb
y
b
