| Restore behavior from 3.9 and earlier when sending non-None to newly started | |
| generator. In 3.9 this did not affect the state of the generator. In 3.10.0 | |
| and 3.10.1 ``gen_func().send(0)`` is equivalent to | |
| ``gen_func().throw(TypeError(...)`` which exhausts the generator. In 3.10.2 | |
| onward, the behavior has been reverted to that of 3.9. |
