> what is your ideal outcome? That the UDF function can take three arguments (and default the fourth value to a constant 1)? I would expect that there exists some value for `stride = Expr` (likely `Expr::Null` or `Expr::Int64(None)`) such that the behavior of calling `expr_fn::array_slice(array, begin, end, stride)` matches the behavior of calling the SQL api **without stride** `select * from array_slice(array, begin, end)`. That way `datafusion-python` can map `stride` to that value when a user calls `f.array_slice(col, literal(2), literal(4), stride=None)` -- This is an automated message from the Apache Git Service.
