[Reflection] Implicit and explicit lambda declaration


#1

I am trying to understand the reflection. I have the following code:

fun main(args: Array) {
println(lengthL1())
println(lengthL2(s))
println(lengthL1.get()) // Error
println(lengthL2.get(s)) // Error

println(lengthNL1.get())
println(lengthNL2.get(s))
println(lengthNL1())
println(lengthNL2(s))

}

val s = “1234”

val lengthL1: () -> Int = s::length
val lengthL2: (String) -> Int = String::length

val lengthNL1 = s::length
val lengthNL2 = String::length

Why I cannot call the get (See Error comments) when I declare the lambda?
Is there any difference between lengthL1 and lenghtNL1?

You can see it in stackoverflow also.
