> 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].
