Target version:

If there is a symbol with the same name as an unused local variable, 
there is no "assigned but unused variable"

=begin
    # no_warning.rb
    def no_warning
      foo = 1
      {:foo => 1}
    end

    def has_warning
      foo = 1
      {:bar => 1}
    end

 $ ruby -v
 ruby 2.0.0dev (2012-11-18) [x86_64-darwin10.8.0]
 $ ruby -w no_warning.rb
 no_warning.rb:8: warning: assigned but unused variable - foo

=end
