Yay - with blocks

with-block.hbs

When you're dealing with nested properties, a with block can define a context so that you don't have to write out the full dotted path. 
The example below shows that inside the block we can directly access the properties of the book like title without typing book.title.  
This is one of my favorite bits of syntactic sugar from VB.NET, glad to see it here.

{{#with book}}
  <div class=”book”>
  <h1>{{title}}</h1>
  {{author}}<br />
  {{text}}</p>
  </div>
{{/with}}
