A async sequence that wraps a single value and emits a new element whenever the element changes.

let sequence = CurrentElementAsyncSequence(0)
print(await sequence.element)

await stream.yield(1)
print(await sequence.element)

await stream.yield(2)
await stream.yield(3)
await stream.yield(4)
print(await sequence.element)

// Prints:
// 0
// 1
// 4
