Subject: Re: Implementation of the object.sort method.

Hi,

I want a demonstrative implementation of the sort method to see how the 
callback (passed block) is handled, specifically the comparison result 
<=>.

For example, in the following code:

puts [4,5,3,2,1].sort do |a,b|
  -1
end

puts [4,5,3,2,1].sort do |a,b|
  1
end

Both print the array sorted down up. I don't understand how this is 
possible so I wanted to see a demonstrative (but factual) implementation 
of the sort method to see how this parameters are handled.

Regards, Jorge
