Yeah, at some point we stopped blaming God for everything. We should do it
again `:-D`

That's precisely why I had to create a "Sum" function for LP variables.
Because I refused to add n variables in n^2 times, and that it is the only
way to do it with __add__ methods. And this "Sum" method fixes the problem
but is a bad solution.
