  1. You are bringing up a good point. It’s true that if you change your class name, you could have some tedious search and replace operations to do depending on the size of your class. But personally it’s a price I’m willing to pay. To me it’s more a matter of clarity than anything else. The fact that you can have the word “self” pointing to different things inside the same class (sometimes to an instance, sometimes to the class itself) just doesn’t please me that much. However, I have to agree that this practice is more convenient in some situations.
    Thanks for your comment
