I noticed this:

class Hash
  def <<(arg)
    self.merge!(arg)
  end
end

x = { :a => 1 }

x.<< :f => 1, :g => 1   # works

x << :h => 1, :i => 1   # syntax error

Is there a way to make the above work? I don't care really since I think the
following is clearer:
x << { :h => 1, :i => 1 }  # my preferred


Cheers,
Simon.
