Yes, this is the trick. I don't have a centralized, fool-proof way of tracking _all_ of the operations which get created. `liveOperations` gave me that.

Given my statement regarding debug-ability above, is there any interest in adding this to the MLIR Python bindings themselves? Or am I the only one who has scars from this issue?

We'd just have to track the set of all `Operation`s which have been created (either constructed from Python or by the bindings while crawling the IR) and haven't been deconstructed yet. Seems like that would be easy in the C++ bindings, wouldn't take up more space than `liveOperations`, and invalidations would be the responsibility of the user.
