There was a problem hiding this comment.
The previous implementation would cause the None value to explode into multiple values(as many as arr.width):
s = pl.Series("a", [[1, 2, None]], dtype=pl.Array(pl.Int64, 3))
s.arr.explode()
shape: (5,)
Series: 'a' [i64]
[
1
2
None
None
None
]This behavior is somewhat unreasonable for me.
