+/**
+ * A multi-binder with guaranteed order.
+ *
+ * <p>
+ * {@link ListBinder} is much like {@link Multibinder}, except it provides a guaranteed iteration order, and binds a
+ * {@link List} instead of a {@link Set}. For example:
+ * </p>
+ *
+ * <pre>
+ * ListBinder<String> listBinder = ListBinder.build(binder(), String.class)
+ * .withDefaultPriority();
+ * listBinder.addBinding().toInstance("a");
+ * listBinder.addBinding().toInstance("b");
+ * </pre>
+ *
+ * <p>
+ * This will create a binding for a {@code List<String>}, which contains {@code "a"} followed by {@code "b"}. It also
+ * creates a binding for {@code List<Provider<String>>} &mdash; this may be useful in more advanced cases to allow list
+ * elements to be lazily loaded.
+ * </p>
+ *
+ * <p>To add an annotation to the list binding, simply write this:</p>
+ *
+ * <pre>
+ * ListBinder<String> listBinder = ListBinder.build(binder(), String.class)
+ * .annotatedWith(Names.named("name"))
+ * .withDefaultPriority();
+ * </pre>
+ *
+ * <p>
+ * and the created binding will be {@code @Named("name") List<String>} instead.
+ * </p>
+ *
+ * <p>
+ * For large lists, it may be helpful to split up their specification across different modules. This is accomplished by
+ * specifying <em>priorities</em> for the {@link ListBinder}s when they are created. For example:
+ * </p>
+ *
+ * <pre>
+ * // In some module
+ * ListBinder<String> listBinder1 = ListBinder.build(binder(), String.class)
+ * .withPriority(0);
+ * listBinder1.addBinding().toInstance("a");
+ * listBinder1.addBinding().toInstance("b");
+ *
+ * // ... some other module
+ * ListBinder<String> listBinder2 = ListBinder.build(binder(), String.class)
+ * .withPriority(1);
+ * listBinder2.addBinding().toInstance("c");
+ * listBinder2.addBinding().toInstance("d");
+ * </pre>
+ *
+ * <p>
+ * The generated list will contain {@code "a"}, {@code "b"}, {@code "c"}, {@code "d"}, in order. This happens because
+ * the first {@link ListBinder} had a smaller priority, so its entries come first. For more information about the
+ * priority system, see {@link Priority}.
+ * </p>
+ *
+ * @param <T> The type of the list element.
