How do you know this *is* the implementation in the base class? How do you know
there *is* a private variable called “_wut”, or its type, or what value it
actually contains, or if there are any other variables that must be set
consistently whenever the value of the “wut” property changes?
I don’t see how you can safely make your change without seeing the source code
of the base class, and it you have access to the source code you’d be better
off making a custom library.
