The Python _pyio.open() function becomes a static method to behave as io.open() built-in function: don't become a bound method when stored as a class variable. It becomes possible since static methods are now callable in Python 3.10. Moreover, _pyio.OpenWrapper becomes a simple alias to _pyio.open. init_set_builtins_open() now sets builtins.open to io.open, rather than setting it to io.OpenWrapper, since OpenWrapper is now an alias to open in the io and _pyio modules.

Can we remove It is not defined in C _io module. So I think it is safe to remove. |

Sure, it was not documented and doesn't exist in the io module. I already removed it: 3bc694d |
