PySequence_Fast_GET_ITEM is defined as: (PyList_Check(o) ? PyList_GET_ITEM(o, i) : PyTuple_GET_ITEM(o, i)) and when using the Limited API we re-define the _GET_ITEM macro to be the _GetItem function, and considering this is our standard use case, the macro could be replaced directly by the function. However, the function returns a new reference, so we need to manually drecrease a reference after the usage, to avoid reference counting issues.
