I have certain methods that I want to proxy, and others that I don't.
I'm marking those that I do want to proxy with an attribute. Rather
than putting the code inside the Proxy class, I was hoping to put it
outside of the class. Not a big deal, but would be nice to be able to
do this.
I've tried adding an IInterceptorSelector, but it doesn't seem to get
called.
