<A>(value: A): (self: SynchronizedRef<A>) => Effect.Effect<A>
<A>(self: SynchronizedRef<A>, value: A): Effect.Effect<A>Sets a new value atomically and returns the previous value, serialized by the ref's semaphore.
When to use
Use to replace a SynchronizedRef with a known value when the previous value
is also needed.

interface SynchronizedRef<in out A>A mutable reference whose update and modify operations are serialized with an
internal semaphore, including effectful transformations.
When to use
Use when shared state may be updated by multiple fibers and each update,
including effectful state transitions, must observe one current value and run
one at a time.
