Summary: Nested generator terminates prematurely

Initial Comment:
def g(x, y):
  for i in x:
    for j in y:
      yield i, j

r2 = (0, 1)
[e for e in g(r2, g(r2, r2))]

Expected result:

[(0, (0, 0)), (0, (0, 1)), (0, (1, 0)), (0, (1, 1)),
 (1, (0, 0)), (1, (0, 1)), (1, (1, 0)), (1, (1, 1))]

Actual result:

[(0, (0, 0)), (0, (0, 1)), (0, (1, 0)), (0, (1, 1))]
