py: Implement support for generalized generator protocol. Iterators and ducktype objects can now be arguments of yield from.
11 years ago
def gen():
yield from (1, 2, 3)
def gen2():
yield from gen()
py: iternext() may not return MP_OBJ_NULL, only MP_OBJ_STOP_ITERATION. Testing for incorrect value led to premature termination of generator containing yield from for such iterator (e.g. "yield from [1, 2]").
