 * <h3>Inference Optimizations (Optional)</h3>
 * When {@code --infer} option is enabled, applies inference optimizations to remove redundant information:
 *

 * serialization of funnels. When possible, it is recommended that funnels be implemented as a
 * single-element enum to maintain serialization guarantees. See Effective Java (2nd Edition), Item
 * 3: "Enforce the singleton property with a private constructor or an enum type". For example:
 *
 * {@snippet :
 * public enum PersonFunnel implements Funnel<Person> {
 *   INSTANCE;
 *   public void funnel(Person person, PrimitiveSink into) {

 * Example usage:
 * <pre>
 * public class CustomModelTransformer implements ModelTransformer {
 *     public Model transformEffectiveModel(Model model) throws ModelTransformerException {
 *         // Add a custom property to all models
 *         model.getProperties().put("custom.timestamp", System.currentTimeMillis());
