I was wondering about the syntax change from 1.8 to 1.9 regarding the
`[]` method

== The source
  class Dictionary
    def self.[](*args)
      args
    end
  end

  p Dictionary[1,2,3,]

== The results
=== For ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-linux]

  [1, 2, 3]


=== For ruby 1.9.0 (2008-09-12 revision 19298) [i686-linux]

  test.rb:7: syntax error, unexpected ']'

I'm not quite sure what the reason behind this change is, but it does
break some of my code between the two versions and it introduces a
syntactic differences between the syntax for array "[]" and "obj[]"
I would be glad if this could be clarified before set into stone.

Thanks in advance,
