Subject: Re: transform hash key from string into symbol

Sorry. Look at Greg's for the keen Ruby way to do it. There should be  
a symmetric stringify_keys for consistency as well.

My hash works as such:

class Hash
   def symbolize_keys
     t = self.dup
     self.clear
     t.each_pair{|k, v| self[k.to_sym] = v}
     self
   end
end

h = {'one' => 1, 'two' => 2}
puts h.symbolize_keys.inspect

{:one=>1, :two=>2}


Again, Greg's is cooler.
