> When defining UDFs the ability to use a function on both scalar and array
> with a single function definition is important. Here using a function just
> written for array-like inputs on scalars is a vital component when providing
> better support. Further more, UDFs need to be consistent with the
> pre-registered functions in the function registry. Considering both usability
> and consistency, it is important to support this feature.
> This requirement was a part of discussion in Scalar UDF integration PR[1].
