   Is it possible to make the `array_slice` function accept a vector as its 
parameter?
   ```rust
   fn array_slice(Vec<Expr>) {
   }
   ```
   When making its UDF function, we need to do
   ```rust
   make_udf_function!(
       ArraySlice,
       array_slice,
       "returns a slice of the array.",
       array_slice_udf
   );
   ```
