I'm not sure this would be an optimization. You'll add checks to PyTuple_GET_ITEM() to select the "kind" of tuple at runtime, and this may very well make things slower. You would need a JIT with type constraints to remove the overhead and truly gain from the optimization. Besides, PyTuple_GET_ITEM() can't really get any faster if all you care about is the *objects* in the tuple, not their value.
