Hi,
I'm not sure what you're trying to actually achieve, but it seems that
you want an identificator for classes, not for instances. In this case,
setting the id should be kept out of __init__ since it is an instance

Hi all,

The only catch I can think of is that nothing prevents a crazy developer
to insort elements using different options to the same list. I foresee
