Subject: (Newbie) Override * on Array

Hi,

I've written a simplistic override of the * operator for Arrays so that
[2,4,6]*[2,2,2] = [4,8,12]

class Array

  def *(other)

    each_with_index do |x,i|
      self[i]= x * other[i]
    end
  end

end

It assumes that the arrays are the same length and no error checking is
done.

My questions are; is this idiomatic Ruby?
What solution  would an experienced Rubyist offer?
How would it be best to handle exceptions when the arrays are of
different dimensions and/or length?


Many Thanks

Mike
