A reactive where the last value can be read at any time.
An initial value must be provided.
constr = Rx.withValue(source, { initial:`hello` }); r.last(); // Read last value
Warning: Since most reactives only active when subscribed to, it's important to also subscribe
to the results of r for this flow to happen. Alternatively, use lazy: 'never' as an option.
