Implications of implementing to_int and to_str in Ruby

I has a class that provides a string value and an int value (exit code and command exit, respectively). In addition to exhibiting through to_sand to_i, I also use to_strand to_int, for example:

class Status
  def to_s
    @output
  end
  alias :to_str :to_s

  def to_i
    @status.exitstatus
  end
  alias :to_int :to_i
end

My idea is to be able to use this object in as many situations as possible. provided that it can be bound to a string or int, this increases usability. For example, I can combine an object with a string:

a_string = "Output was: " + results

(I wanted to use this as an example of int-enforcement, but Fixnum. + Doesn't like it, so it actually doesn't work :)

an_int = 1 + results
