That doesn't look like an inheritance relationship ("is a").
If you say "from now on, act as a PClass, until further notice" and later 
"now, act as a NClass" you're using the Strategy pattern.
If you decide at every invocation which method to call, it's a dispatcher; 
you may use a dictionary to map each alternative to the function to be 
invoked. If it only depends on the type of the argument, there is a hidden 
gem in pkgutil (simplegeneric) that can help you.
