You're welcome.  I just had one spelling error:

irb(main):012:0> h = Hash.new {|ha,k| h[k] = ""}

should have been

irb(main):012:0> h = Hash.new {|ha,k| ha[k] = ""}

It does not make a difference in this case (since ha == h) but the
corrected version is more robust (i.e. if someone reassigns h).

Kind regards

robert
