Thank you for the explanation! Will give it a shot.

P.S. Yes it works! Perhaps add a comments in the short version where it says

//This shortened version does not compile, use the GitHub version of the code

It said "proof-of-concept" and I generally expect PoC to work as presented. My bad for not reading everything carefully.

Good idea, I've added the comment
