I don't mind the separate methods, but if I did... :-)  I wouldn't want
the context to be the determinant.  For one thing, you might want to
return a mapped array:

  def add_three(a)
    a.map {|e| e + 3}
  end

where you wouldn't want the receiver automatically modified.

Can you explain what you mean by a special generic method?
