Unsupported Features

Stache

• [ ] {{3}} looking up the 4th item in an array (assuming there is an array in the scope)
• [ ] Skipping the protections around img srcs like: <img src="{{image}}"/>. These can be changed to src:from.
• [ ] @index being a helper that can add an offset like: <ul>{{#each list}}<li>{{@index 5}} {{.}}</li>{{/each}}</ul>
• [ ] @index use %index
• [ ] joinBase {{joinBase 'hello/' name}}
• [ ] options 2nd argument to stache .subtemplate (we should get a warning here). Also scope.options for both custom tags and attributes.
• [x] call expressions

Utils

• [ ] jQuery can make normal objects "bindable". If this is something that's wanted, we might want to use SimpleMap or mixin eventQueue(object)

Component

• [ ] complex nesting of <content/> element. How common is <content>? I can spend time making some edge cases work, but I'm skipping for now.
• [ ] hyphen-less tag names <tabs> defined after the template.
• [x] https://github.com/canjs/canjs/pull/1803 Calling destroy before event handlers are unbound.
• [ ] p3='{{v3}}' use normal bindings instead ... don't rely on automatic attribute bindings.

Control

If a can-23 control wants to opt into using the CanJS 6 removed event, you need to add:

Control.extend({
  " removed": function(){ ... }
  $useAsyncRemoved: true
})

This can be set globally like:

Control.$useAsyncRemoved = true

You need to import util/before-remove to get the beforeRemove event and control to make removed use beforeRemoved by default.
