Yes, looks like the linked PR fixed the issue. I have rebuilt PyArrow on
main and the code works:
```python
In [1]: import pyarrow
In [2]: pyarrow.__version__
Out[2]: '23.0.0.dev83+g9dfc3afb2'
In [3]: struct_type = pyarrow.struct([("x", pyarrow.int64()), ("y",
pyarrow.int64())])
...:
...: list0 = [{"x": 1, "y": 2}, {"x": 3, "y": 4}]
...: list1 = [{"x": 5, "y": 6}]
...: list2 = [{"x": 7, "y": 8}, {"x": 9, "y": 10}]
...:
...: list_of_structs = pyarrow.array([list0, list1, list2],
type=pyarrow.list_(struct_type))
...:
...: # Get the first list - should be [{x:1,y:2}, {x:3,y:4}]
...: elem0 = list_of_structs[0]
...: batch_for_elem0 = pyarrow.RecordBatch.from_struct_array(elem0.values)
...:
...: print("ver", pyarrow.__version__)
...: print("RIGHT:", len(elem0.values), elem0.values.field("x"))
...:
...: print("WRONG?:", len(batch_for_elem0), batch_for_elem0["x"])
ver 23.0.0.dev83+g9dfc3afb2
RIGHT: 2 [
1,
3
]
WRONG?: 2 [
1,
3
]
```
I think a test on the PyArrow side would still be needed so I will keep this
issue open. Contributions welcome!
