Greenlet won't compile on anything older than Python 3.11 alpha 4 (see

https://bugs.python.org/issue46090). Summary of breaking internal changes:
|
|
- Python 3.11 alpha 1 changed how frame objects are represented internally.
|
|
- https://github.com/python/cpython/pull/30122
|
|
- Python 3.11 alpha 3 changed how recursion limits are stored.
|
|
- https://github.com/python/cpython/pull/29524
|
|
- Python 3.11 alpha 4 changed how exception state is stored. It also includes a
|
|
change to help greenlet save and restore the interpreter frame "data stack".
