It is very useful in cases when you need to handle multiple objects , instead of having arrays for all kinds of variables and then managing those arrays in methods you can just write a class to handle one object and then make many instances of that class. This also gives the namespace resolution to the variables so that you can avoid using global variables and still use variables across procedures.
