Using Nested Effects Outside `Effect.gen` with Preemptive Execution

Can I do the following:

eff = Effect.sync(() => {
  // ...
  Effect.log(logMessage).pipe(Effect.runSync);
  // ...
});

Effect.runSync(eff);

eff = Effect.sync(() => {
  // ...
  Effect.log(logMessage).pipe(Effect.runSync);
  // ...
});

Effect.runSync(eff);

In other words, can I use nested effects without

Effect.gen

Effect.gen

if I preempt the execution of the inner effect?
