C# like function/xml docs for UDFs.

Hi Team,
Wasn't sure a nice place to put this so trying out the discussions feature of Github.
I have been playing a lot of with upcoming UDFs in new formula bar and one thing i noticed that we do not have a good signature help for UDFs. Look below for an example

I was thinking if the comments could re-purposed in UDF syntax to serve as a way to add description of the UDFS being defined which might include parameter descriptions and return values similar to what C# does. If there are plans for that then this can be ignored but sharing something that has been running in my mind.
