Subject: Subselecting hash back into hash (oneliner?)

Going through pick-axe and was just wondering if there was a one  
liner for something such as this that I may have missed:

h2 = Hash.new
h1 = {"foo1"=>"bar1", "foo2"=>"bar2"}
query = h1.select { |k,v| v == "bar2" }
query.each do |result|
   h2[result[0]] = result[1]
end
p h2

Thanks.
