> As I first mentioned in my post[1] on comp.lang.python, it seems possible to modify a dict while a lookup is ongoing, without causing the lookup to restart.

That's a bad practice. Python dict raises an exception in some cases: RuntimeError("dict mutated during update").

Detecting any change during a lookup would slow down, whereas dict performance is key in Python performance in general, since dict is used everywhere for Python namespaces.

I close the issue as "wont fix".
