regarding inline classes (https://github.com/Kotlin/KEEP/blob/master/proposals/inline-classes.md), why Name? gets mapped to String instead String?..?

inline class Name(val s: String)
fun foo(n: Name?) { ... } // `Name?` here is mapped to String

[Pavlo Liapota]

may be it is String in byte code?

[gildor]

There is no String? in bytecode, nullable types is compiler only feature + generated asserts to check nullability
