I'd like to suggest "outer v" for this.  The behavior could be to scan
outward for the first definition of v.  If the only outer-scope variable
is at module-level, then the behavior would be the same as "global v".
Or if everyone is comfortable enough re-using the keyword "global", then
I also like "global v in f".
