    Minutes.new(@count + o.to_i)

  def *(o)
    Minutes.new(@count * o.to_i)
  end

  def /(o)
    Minutes.new(@count / o.to_i)
  end

    [Minutes.new(@count), Minutes.new(x.to_i)]

m = Minutes.new(5)

p(m + 8)
p(m - 2)
p(m * 2)
p(m / 2)

Is it normal to call the new again on the lhs in coerce? I usually put self there.

Oh yeah, should be self there.

Didn't know if I was missing something that would blow my mind. BTW, I've wanted to thank you for a while. Thanks for getting my friend an interpreter for RubyConf last year. He had the best time.

No problem! Glad it worked out. Do you know if he's planning on coming to RubyConf this year?

I have no idea. I'll ask him right now.

K. hit me back up on twitter when you find out.
