Then in what circumstances will getself NOT be called? What is the point of having an object, if literally every reference to it will result in something else being used?
I think Yanghao has misunderstood the proposal. What Nate actually proposed is not that every time the value is accessed it calls __getself__, only accesses that are loads from a variable. The infinite regress problem is no worse than, say, __getattribute__ usually needing to call a method on super or object.
But if I’m right, then your initial refactoring point is still unanswered. You can return or otherwise use the value of self or the return of the uncloak function or whatever without triggering another call to __getself__, but if you refactor the return statement by storing an intermediate value in a temporary local variable, accessing that variable will trigger another call to __getself__. I assume Nate is working on an answer to that along with all the other points that have been raised.
