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".
