.. versionadded:: 3.11
.. opcode:: CHECK_EG_MATCH
Performs exception matching for ``except*``. Applies ``split(TOS)`` on
the exception group representing TOS1.
In case of a match, pops two items from the stack and pushes the
non-matching subgroup (``None`` in case of full match) followed by the
matching subgroup. When there is no match, pops one item (the match
type) and pushes ``None``.
.. versionadded:: 3.11
.. opcode:: PREP_RERAISE_STAR
Combines the raised and reraised exceptions list from TOS, into an exception
group to propagate from a try-except* block. Uses the original exception
group from TOS1 to reconstruct the structure of reraised exceptions. Pops
two items from the stack and pushes the exception to reraise or ``None``
if there isn't one.
.. versionadded:: 3.11
.. opcode:: WITH_EXCEPT_START
Calls the function in position 4 on the stack with arguments (type, val, tb)

Performs exception matching for ``except*``. Applies ``split(TOS)`` on

Pops one item from the stack (the match type). If a match was found,
next item (the exception) and pushes the non-matching part of the
exception group followed by the matching part.

If TOS is not none, sets the bytecode counter to *target*. TOS is popped.
