10/26/2019, 12:34 PMit was discussed a bit already here: https://kotlinlang.slack.com/archives/CJLTWPH7S/p1571861819250900?thread_ts=1571859974.243400&cid=CJLTWPH7S

Sure, that makes a lot of sense
But as you’re doing on param-less function, you can get default value for those things
and accept default params from function with them
