I still think that the use of a keyword like "static" would be easiest.

And in this case static just means that it's a variable only readable
inside foo() and it should maintain it's value between calls. A "global"
without the name pollution. Or is this too simple .... ???
No, it's not "too simple" an example/request.
Although they are often considered more complex than materials suitable
for 'beginner' (?simple) training, generator functions (and
async-gen-func-s) already offer this (without the static-statement)
def gen( args ):
counter = 0
while counter < max_depth:
yield counter
counter will retain its value ("maintain state") between iterations.
