apologies if this has been asked before: couldn't find in search.  Is there a setting for enforcing explicit return type declaration on all functions?  I think this would help my team's readability.  Specifically this often gets omitted in Single Expression Functions `fun myFun(a,b) = logic()`.  Rather than police improper usage of single expression i thought it'd just be easier to enforce return types across the board.

I don't see one either. One issue is it would require functions that don't really return anything, to return a Unit. Unless the processor really digs in and determines the function doesn't return. Perhaps it does.

At this point, it's a feature request, or you create a custom rule and ideally contribute it. I'm sure thee are others that would turn this on for public functions definitely.

There's none at the moment. This might be a good idea for a custom rule.
