After Fantom I miss function compatibility. Look section "Type Compatibility" at fantom.org/doc/docLang/Functions
fun process(fn:()->Unit){...}
val can:()->Boolean = {true}
process(can) // this is not compiled: Type mismatch: inferred type is () -> kotlin.Boolean but () -> kotlin.Unit was expected
//expect: compiled as process{can()}
// and
val addOne:(Int)->Int = {it+1}
fun mult(num:Int,fn:(Int,Int)->Int) = {…}
mult(2,addOne) // this dont compile
//expect: compiled as mult(2){a,b -> addOne(a)}
What u think about function compatibility for Kotlin?
