MoveSemantics

NB: Certain write operations' consistency is affected by faithful support of these semantics, thus their consistency/atomicity is as good as the support of these semantics by the interpreter.

Currently, this allows us to implement all the write scenarios in terms of append and move, however if this proves too difficult to support by backends, we may want to relax the move semantics and instead add additional primitive operations for the conditional write operations.

object FailIfExists extends MoveSemantics with Product with Serializable

Indicates the move should (atomically, if possible) fail if the destination exists.
object FailIfMissing extends MoveSemantics with Product with Serializable

Indicates the move should (atomically, if possible) fail unless the destination exists, overwriting it otherwise.
object Overwrite extends MoveSemantics with Product with Serializable

Indicates the move operation should overwrite anything at the destination, creating it if it doesn't exist.
