Subject: Rjudy & Ruby 1.8.0;

Hi,

	I just now looked at rjudy-1.0 and Ruby 1.8.0.
It looks as if the Hash implementation in Ruby 1.8.0 is good :-).

I generate a 3.3 MB junk file:
for i in 1..500000
  puts i  end



Then I run
ruby words.rb  /tmp/junk
(words.rb is from rjudy-1.0/examples)
and get:


*** Insertion Times for 500000 words ***
