- I wonder whether the shared keys could be computed at compile time, considering all attribute names that get assigned for self. The compiler could list those in the code object, and class creation could iterate over all methods (taking base classes into account). This is hard, because sometimes you don't quite know what the self is even, especially if init calls some methods or there is any sort of control flow. You can however track what gets assigned at runtime at have shapes associated with objects.

Actually, it's fairly easy, as it only needs to be heuristical. I am proposing the exact heuristics as specified above ("attribute names that get assigned for self").

I don't think that init calling methods is much of an issue here, since these methods then still have attributes assigned to self.
