New submission from Antony Lee <[email protected]>:
Unlike `PySequence_GetItem`, `PyTuple_GetItem` does not support negative
indices ("indexing from the end"). That is fine, but warrants a notice in the
docs (as that behavior is certainly not obvious).
The same wording as for `PyList_GetItem` (changing "list" to "tuple") should be
good enough (`PyList_GetItem` currently states: "The position must be
non-negative; indexing from the end of the list is not supported. If index is
out of bounds (<0 or >=len(list)), return NULL and set an IndexError
exception.")
