   @matriv for your comments about nulls, all those are good questions. I tried to follow what was implemented in the old stack, but i guess the question here is whether our udfs should be "relaxed" for nulls and accept nulls, returning nulls, or if we should enforce non null.
   
   Also _I'm pretty sure_, but i need to double check it, that the runtime accepts nullable args for these functions
