Yes, you are completely right :)

But anyway, I think no newbie will read the doc of a integer since probably a 
newbie will no realize of the class nature of a integer in Ruby, completely 
different of any other language.
That's wahy I suggested to explain all this stuf in a Ruby manual instead of 
core doc.
