compact Modifier

Converts a comma-delimited list of variable names into an array that can be used anywhere. Arrays are accepted.

It allows colon delimited syntax to target nested variables.

title: 'The finest title there ever was'
stuff:
  one: 'Value One'
  two: 'Value Two'

{{ "stuff:one, title, stuff:two" | compact | ul }}

Would produce the following output:

<ul>
    <li>Value One</li>
    <li>The finest title there ever was</li>
    <li>Value Two</li>
</ul>

$foo = 'bar';
$baz = 'qux';
compact('foo', 'baz'); // ['bar', 'qux']
