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".

Is this something that should be taken up on python-dev?

I don't believe there's anything to debate on this, so all it really needs is a 
patch, followed by getting someone to review and commit it.
