Subject: << for Hash?

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

Eg,

thing = {
  :foo => 1,
}

thing << {
  :bar => 2,
   :baz => 3,
}

thing #=> {:foo=>1, :bar=>2, :baz=>3 }


Of course it overwrites existing keys. I think it's a little sexier than

thing.merge!({
   :bar => 2,
   :baz => 3,
})

or
 thing[:bar] = 1
thing[:baz] = 3


Is it safe to use this? Is there some good reason why << is not already
defined for Hash?
