    11*SVN*

     3* Enhance Symbol#to_proc so it works with list objects, such as multi-dimensional arrays. Closes #5295 [nov@yo.rim.or.jp].  Example: 
     4 
     5    {1 => "one", 2 => "two", 3 => "three"}.sort_by(&:first).map(&:last) 
     6    #=> ["one", "two", "three"] 
    27 
    38* Added Hash.create_from_xml(string) which will create a hash from a XML string and even typecast if possible [DHH]. Example: 

  • trunk/activesupport/lib/active_support/core_ext/symbol.rb

    10     Proc.new { |obj, *args| obj.send(self, *args) } 
     10    Proc.new { |*args| args.shift.__send__(self, *args) }
