Class-level variables - a scoping issue

[Gregory Ewing]

If you can’t do it statically, do it dynamically.

But how can that be done without seeing into the future?

“Dynamically†is when that “future†becomes the present, so you can see it
right in front of you, here, now.

“Dynamically†is when that “future†becomes the present, so you can see it
right in front of you, here, now.

But raising an "UnboundAttributeError" when attempting to
read a class attribute that *could*, but hasn't yet, been
shadowed by an instance attribute requires taking action
*before* the future becomes the present.

Unless I've misunderstood what you were suggesting the
behaviour should be.
