Tuples? Really?

Ok, quoting PEP-620:
> Members of … PyTupleObject structures have not changed since the "Initial revision" commit (1990)

I honestly think the reason for that might simply be that there's not so much to improve for tuples.

I certainly understand that that is a problem, especially if "PyObject" may change in the future. And this is essentially what the current "PyTuple_GET_ITEM()" macro does in a binary module.

Should we also turn "_PyTuple_ITEMS()" into a public inline function then to make up for the loss of the "&PyTuple_GET_ITEM(t, 0)" pattern? It would make it explicit what is intended. I think that should be our main goal in the CPython side.
