Ah OK, that makes sense of it then :)

> But the most important thing is that using PyLong_FromUnsignedLong() instead of _PyLong_FromUnsignedChar() on top of GH-15192 is producing the same results: striter_next() uses small_ints[] directly. However that's not true for bytearrayiter_next(): PyLong_FromUnsignedLong() is called there. I think that's due to how code is profiled so I'm satisfied with these results more or less.

Very interesting! That's a good comparison to have made, too.

I agree with your conclusions.
