Well, "permanent temporary file" does sound odd.
By the way, NamedTemporaryFile returns a proxy instead of the file itself.
In some rare cases that could be a problem.
Would mktemp() really be dangerous if you used it like this,
def new_game(directory):
for _retry in range(3):
filename = mktemp("game_", ".json", dir=directory)
try:
return open(filename, "x")
except FileExistsError:
pass
raise FileExistsError
with the "x" mode?
