Are you in an environment where the compiler / interpreter can do CSE across string-indexed dictionaries? If not, this code seems like it's gratuitously doing two extra dictionary lookups vs. an implementation using temporary variables. Now you may very well, and rightly, say "who cares" -- but to me, this is where I'd really see something like Copilot contribute. The example you gave saves typing, but leads to equal or lower quality "correct" code to what you would write anyway with a few more keystrokes -- but a system that could advise to consider the alternate version (with the human in the loop to confirm semantic equivalence for the particular dictionary in use, since the compiler / interpreter / advice tool probably cannot) would lead to not just more code per minute, but better code.
