The keyword typo suggestion mechanism in traceback would incorrectly
suggest replacements when the extracted source code was merely incomplete
rather than containing an actual typo. For example, when a missing comma
caused a syntax error, the system would suggest replacing 'print' with
'not' because the incomplete code snippet happened to pass validation.
The fix adds a validation step that first checks whether the original
extracted code raises a SyntaxError. If the code compiles successfully
or is simply incomplete (compile_command returns None), the function
returns early since there is no way to verify that a keyword replacement
would actually fix the problem.
Default implementation of sys.unraisablehook() now uses traceback._print_exception_bltin() to print exceptions with colorized text.

As it says in its documentation, walk_stack was meant to just
follow `f.f_back` like other functions in the traceback module.
Instead it was previously doing `f.f_back.f_back` and then this
changed to `f_back.f_back.f_back.f_back' in Python 3.11 breaking
its behavior for external users.
This happened because the walk_stack function never really had
any good direct tests and its only consumer in the traceback module was
`extract_stack` which passed the result into `StackSummary.extract`.
As a generator, it was previously capturing the state of the stack
when it was first iterated over, rather than the stack when `walk_stack`
was called. Meaning when called inside the two method deep
`extract` and `extract_stack` calls, two `f_back`s were needed.
When 3.11 modified the sequence of calls in `extract`, two more
`f_back`s were needed to make the tests happy.
This changes the generator to capture the stack when `walk_stack` is
called, rather than when it is first iterated over. Since this is
technically a breaking change in behavior, there is a versionchanged
to the documentation. In practice, this is unlikely to break anyone,
you would have been needing to store the result of `walk_stack` and
expecting it to change.
Previously, `traceback.print_list` didn't have a documentation entry and was not exposed in `traceback.__all__`. Now it has a documentation entry and is exposed in `__all__`.
