title: Implementing a decorator to limit setters
body: <p>I have a class with a handful of instance variables, which I set through functions decorated with the <code>@someinstancevariable.setter</code> decorators. How would I go about ensuring that the values set have a maximum and a minimum value to which they could be set? And would I need to have multiple decorators for this or is there some way I can use the regular <code>@someinstancevariable.setter</code> decorator and override it?</p>
