Receiving object reference support - Transfer to object input param

[nikos-kitmeridis]

To my understanding Receiving inputs are not currently supported.
I only see shared and ImmOrOwned

public enum ObjectArg: KeyProtocol {
    /// Represents an object argument that is either immutable or owned by the caller.
    case immOrOwned(ImmOrOwned)

    /// Represents a shared object argument.
    case shared(SharedObjectArg)

I wonder if it would be possible to add it.

Thanks!
