The single quotes are no accident...

This doesn't do the same thing.

No.  This question is *when* does the string get evaluated.  In your
example it got evaluated immediately and never again.  In my example,
it did not get evaluated immediately, and with my patch, it will be
re-evaluated each time the the prompt is printed.
