Now in Kotlin we can write:
fun log(str:String) = println("$str in fun")
val log = { str: String -> println("$str in lambda") }
log("hello")
What will be output?
And what is the difference if we omit parens:
log "hello" ?

Logger functions is not very good example. Look at await, yield. Suspending call isn't ordinary and dropping parens so they would look like keywords (with IDE colored highlighting) would be a good idea
