 *   <li>It doesn't propagate exceptions, so apps don't have a way to react to them.
 *   <li>It doesn't interoperate well with RxJava, coroutines, and other more commonly used
 *       alternatives.
 *   <li>It imposes requirements on the lifecycle of its subscribers. For example, if an event
 *       occurs between when one subscriber is removed and the next subscriber is added, the event
 *       is dropped.

 *
 * <p>For instance, if <i>steps</i> is 5, one example sequence that will be tested is:
 *
 * <ol>
 *   <li>remove();
 *   <li>hasNext()
 *   <li>hasNext();
 *   <li>remove();
 *   <li>next();
 * </ol>

 * <p>This particular order of operations may be unrealistic, and testing all 3^5 of them may be

 * <p>Key Features:
 * <ul>
 *   <li>Automatically reloads properties if the file is modified.</li>
 *   <li>Supports custom check intervals for file modification checks.</li>
 *   <li>Provides synchronized methods for loading and storing properties.</li>
 *   <li>Extends {@link Properties} and overrides its methods to work with dynamic properties.</li>
