  * Support for observing changes in model-view architectures.

  * **Warning:** This library is experimental, and APIs are subject to change.

  * This library is used to observe changes to [Observable] types. It also

  *
  * *Note*: it is good practice to keep `@reflectable` annotation on

  * preserve all of its members for reflection.

  * [Tools](https://www.dartlang.org/polymer-dart/) exist to convert the first
  * form into the second form automatically, to get the best of both worlds.

remove "is"/rephrase?

Done.

+// ...which underlies TemplateBinding. Since we don't need all of the
+// functionality of observe-js, we port what is needed for data bindings.
+// Most of the functionality is implemented, except where differences are needed
+// due to Dart's different Observable functionality.
