Exercises

If you want to get some practice writing very flexible decorators that work with and without arguments, take a look at the exercises from the section on decorators with arguments. Redo all of them, and for each exercise make sure your decorator can be used in all three ways:

@dec
@dec()
@dec(arg1, arg2, ...)

Note that this means you will also have to come up with some reasonable default values for each decorator.
