I am +1 for this solution suggested by @Michael-J-Ward
```rust
#[doc = "returns a slice of the array."]
pub fn array_slice(array: Expr, begin: Expr, end: Expr, stride:
Option<Expr>) -> Expr {
if let Some(stride) = stride {
Expr::ScalarFunction(ScalarFunction::new_udf(
array_slice_udf(),
vec![array, begin, end, stride],
))
} else {
Expr::ScalarFunction(ScalarFunction::new_udf(
array_slice_udf(),
vec![array, begin, end],
))
}
}
```
