Subject: re-assign variable to another object without causing error message.

I have a loop that will updated a variable whenever there is 
a change. But I have found that I am given an error. It runs and the 
result is correct but it would like to get rid of the error. After simplifying
the code, the fundamental problem is the following code:


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

m.rb:26: warning: already initialized constant P

class Column 
  attr_accessor(:elements)

  def initialize(a)
      @elements = a
  end

  def *(m) 
      result = Column.new(4)    
      result.elements  = self.elements * m
      return result
  end

end


R = Column.new(3)

P = R 
P = P * 2





What is the 'correct' way of doing it? Thanks.

Hubert
