 /**
+ * The `For` directive instantiates a template once per item from an iterable. The context for each
+ * instantiated template inherits from the outer context with the given loop variable set to the
+ * current item from the iterable.
+ *
+ * It is possible to alias the `index` to a local variable that will be set to the current loop
+ * iteration in the template context.
+ *
+ * When the contents of the iterator changes, `For` makes the corresponding changes to the DOM:
+ *
+ * * When an item is added, a new instance of the template is added to the DOM.
+ * * When an item is removed, its template instance is removed from the DOM.
+ * * When items are reordered, their respective templates are reordered in the DOM.
+ *
+ * # Example
+ *
+ * ```
+ * <ul>
+ *   <li *for="error in errors; #i = index">
+ *     Error {{i}} of {{errors.length}}: {{error.message}}
+ *   </li>
+ * </ul>
+ * ```
+ *
+ * # Syntax
+ *
+ * - `<li *for="#item of items; #i = index">...</li>`
+ * - `<li template="for #item of items; #i=index">...</li>`
+ * - `<template [for]="#item" [of]="items" #i="index"><li>...</li></template>`
