Let me give you an example.
#module eggs
eggs_var = 0 # a variable, maybe a counter or similar
EGGS_CONST # a constant
#module spam
import eggs
spam_var # Another variable
def foo():
use(eggs.EGGS_CONST)
-------------
We will want to treat `eggs.EGGS_CONST` as a constant.
To do that we need to be notified if `spam.eggs` or `eggs.EGGS_CONST` changes,
but we do not want be notified whenever `spam.spam_var` or `eggs.eggs_var`
changes.
This might not be necessary for us right now, but we will want to implement
optimizations over larger regions than a single bytecode in 3.12.
