The following opcodes have been added, see [0] for details: - LIST_TO_TUPLE: convert a list to a tuple, use for constructing lists/tuples in some cases. - LIST_EXTEND: use for constructing lists with unpacking. - SET_UPDATE: use for constructing sets with unpacking. - CONTAINS_OP: check if `a in b` generally useful. When writing tests these op-codes where needed for basic operations and can be safely supported. Add note why dictionary manipulation op-codes have been left out. Also restrict namsepace access to anything with an underscore prefix since these may be undocumented. [0]: https://docs.python.org/3.10/library/dis.html
