There is no infinite recursion. The for loop is currently implemented as

# handle iterators through an idempotent iter()
tmp = iter(xs)
# here you must check that tmp actually implements the iterator protocol,

while True:
try:
x = next(tmp)
except StopIteration:
break
# use x
If I understand you correctly you suggest the following:
# expect an iterator
# fall back to getting an iterator through iter()
try:
tmp = xs.__next__
except AttributeError:
tmp = iter(xs).__next__
while True:
try:
x = tmp()
except StopIteration:
break
How is that simpler?
see above
