Interesting!  Although the example with a len() and mutable default arguments 
obscured the utility, I thought.  Also, why limit it to one assignment?

Liked Terry's suggestions for name.  The name that jumped into my brain as I 
read was a reuse of the locals() or globals() callable with key words, that 
would change their behavior to what you suggest.
