What would you do in this case val dowNotNull: DayOfWeek = parcel.readEnum<DayOfWeek>() if readInt() returns 0? I think you need two implementations anyway

[Paul Woitaschek]

throw an exception

[robstoll]

So depending on the chosen T you throw or not right? You definitely need two implementations. But you could provide two overloads, so it reads natural to the consumer of your function

[Paul Woitaschek]

You can't add overloads because the nullity type doesn't exist on bytecode level

[robstoll]

ah you're right

[gildor]

But you can use JvmName to avoid name conflict

[robstoll]

In this case this does not help because you have the ambiguity in Kotlin itself
