There are a couple of other facets of the example you should take note of:

 * `+=` allows you to append paths and collections of paths to `compileClasspath` and `runtimeClasspath` instead of overwriting them

  // that contains line breaks, then the validation failure message will also be produced as if the messageExpression field were unset, and
  // the fact that messageExpression produced an empty string/string with only spaces/string with line breaks will be logged.

	// as running, while filters like pod affinity are more likely to fail when
	// the nominated pods are treated as not running. We can't just assume the
	// nominated pods are running because they are not running right now and in fact,
	// they may end up getting scheduled to a different node.
	logger := klog.FromContext(ctx)
	logger = klog.LoggerWithName(logger, "FilterWithNominatedPods")
	ctx = klog.NewContext(ctx, logger)
	for i := 0; i < 2; i++ {

	// Not counting the final S in each (which overlaps the first S in the next),
	// This works out to an average length 2×½ + 3×¼ + 4×⅛ + ... = 3.
	// The space we need is further reduced by the fact that many of the
	// short patterns like SLS will often be the same character sequences
	// repeated throughout the text, reducing maxID relative to numLMS.
	//

	}

	// SPECIAL CASE: For service accounts, any valid JSON is allowed as a
	// policy, regardless of whether the number of statements is 0, this
	// includes `null`, `{}` and `{"Statement": null}`. In fact, MinIO Console
	// sends `null` when no policy is set and the intended behavior is that the
	// service account should inherit parent policy.
	//
	// However, for a policy like `{"Statement":[]}`, the intention is to not

	// GoSwitch and GoSwitchDestroy represent a trio of events:
	// - Unblock of the goroutine to switch to.
	// - Block or destroy of the current goroutine.
	// - Start executing the next goroutine.
	//
	// Because it acts like a GoStart for the next goroutine, we can
	// only advance it if the sequence numbers line up.
	//
	// The current goroutine on the thread must be actively running.

	// 3. Trigger cycle N+1 by starting sweep termination N+1.
	//
	// 4. Wait for mark termination N+1 to complete.
	//
	// 5. Help with sweep N+1 until it's done.
	//
	// This all has to be written to deal with the fact that the
	// GC may move ahead on its own. For example, when we block
	// until mark termination N, we may wake up in cycle N+2.

	// Wait until the current sweep termination, mark, and mark
	// termination complete.

	// headroom when the GC actually starts. For larger heaps, set the max trigger
	// point at the goal, minus the minimum heap size.
	//
	// This choice follows from the fact that the minimum heap size is chosen
	// to reflect the costs of a GC with no work to do. With a large heap but
	// very little scan work to perform, this gives us exactly as much runway
	// as we would need, in the worst case.

	// that contains line breaks, then the validation failure message will also be produced as if the messageExpression field were unset, and
	// the fact that messageExpression produced an empty string/string with only spaces/string with line breaks will be logged.
