+/**
+ * A library for observing changes to observable Dart objects.
+ * Similar in spirit to EcmaScript 6
+ * [Object.observe](http://wiki.ecmascript.org/doku.php?id=harmony:observe), but
+ * able to observe expressions as well as objects, so long as the expressions
+ * are computed from observable objects.
+ *
+ * See the [observable] annotation, [Observable] base class, and the [observe]
+ * function.

+// TODO(jmesserly): this library is independent of web_ui, and can be factored
+// out into its own package. However, the compiler transform for @observable
+// requires web_ui compiler, until we get buildtool support for it.
