Subject: Unexpected Hash#first return under Ruby1.9

Hi, Ruby 1.9 implements "first" method for Hash (as Hash are ordered now).
However the return value if a bit annoying for me. A real example:

irb> h = {"aaa"=>"AAA", "bbb"=>"BBB"}
irb> h.first
["aaa", "AAA"]


I want a method that returns the first value of a hash, rather than an array 
containing the first hash element and value. Does such method exist?

Unfortunatelly RDoc for Hash under Ruby 1.9 seems not to exist yet:

  http://ruby-doc.org/core-1.9/

Thanks.
