If you are attending the conference but relatively new to the language it is an excellent way to get up to speed on the language and its idioms.

Say you have a function
fun sum(x: Int, y: Int) = x + y and for some reason you suspect that it is going wrong. You’d like to print the return value to the console. So you extract the expression to a variable, print it, and return it.
fun sum(x: Int, y: Int): Int { val result = x + y println(result) return result } Hmmm, for a temporary change, that escalated pretty quickly. We could...
