Subject: keeping a hash' sort order?

hi -

sure this is a common question...
i have a hash of stuff that i want to load/keep in a particular order.

irb(main):005:0> hsh =  { "one" => 1, "two" => 2, "three" => 3,
"four"=>4, "twentythree"=>23 }

gives back:
=> {"three"=>3, "two"=>2, "twentythree"=>23, "one"=>1, "four"=>4}

ruby sorts the hash in apparent random order (by object id?)

how can i keep the items in the order i want?

someone said i should probly not use a hash at all? however, i do want
to keep the items organized in the order like above, but access thru
hashkeys.

hsh.each_pair{ |tag, val| ...

can i use a more complex structure and sort by some internal key?

thanks!
