I don't think this is implementation-dependent.
The docs say that it is:
https://docs.python.org/3/reference/simple_stmts.html#the-global-statement
Names listed in a global statement MUST NOT [emphasis added] be
defined as formal parameters or in a for loop control target,
class definition, function definition, or import statement.
CPython implementation detail: The current implementation does not
enforce the two restrictions, but programs should not abuse this
freedom, as future implementations may enforce them or silently
change the meaning of the program.
Ah, good. TIL! :)
