Re: [w3c/webcomponents] [templates] What is declareCallback? (#693)

To offer an example related to what @justinfagnani suggested about one-time work:

Many types of template expressions will need to be parsed before they can be used in the template processor. It will be ideal if each expression is only parsed once per part per unique template. A `declareCallback` would be a nice spot to do this kind of thing.
