Hello guys,
given Java interface interface Foo { int bar(); }
why do I need an explicit labeled return in Kotlin when using SAM conversion when creating a property - instance of this interface:
val foo = Foo { return@Foo 5}
why cannot I just write:
val foo = Foo { return 5 }

I know that I can just write it as val foo = Foo { 5 }, but I wonder why I need the labeled return in the second example

arkadiy: This is a statement not expression.

[radityagumay]

arkadiy: that's why, they need to @ to return a value, you can omit it

@radityagumay Could you elaborate more, please?
