      The constituent values of an SBE value::Array or value::ArraySet are always owned by the array. Imagine that a caller wants to assume ownership of one of these constituent values. At the moment, the only way that the caller can do so is to make a copy. The goal of this ticket is to improve the API to allow moving values of out a value::Array or value::ArraySet.

      Such an API is dangerous and should be used with caution. The caller must be certain that they have ownership of the value::Array or value::ArraySet, since this precludes the possibility of other code holding a view into the array that would be invalidated by the move operation.
