Hi all,
The documentation at https://docs.python.org/3/reference/simple_stmts.html
says that:
"Names listed in a global statement must not be used in the same code block
textually preceding that global statement"
But then later:
"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..."
Code like this
def f():
x = 1
global x
gives SyntaxWarning for several releases, maybe it is time to make it a
SyntaxError?
(I have opened an issue for this http://bugs.python.org/issue27999 I will
submit a patch soon).
