Some KRL statements and expressions use extended quotes. Extended quotes allow multiple line passages that contain the double quote symbol (") to be more easily entered.
There are two types of extended quotes in KRL:

Chevrons

Chevrons enclose the items to be quoted in double less-than and greater-than signs (<<...>>). For example:

somevar = <<
<p>This is <em>some</em> HTML.<br/>
<a href="http://www.google.com">Search Google</a>
</p>
>>;

Values inside chevrons are treated as strings. The white space is preserved.

Clown Hats

Clown hats are used to quote JavaScript (<|...|>). The primary difference between chevrons and clown hats is that non-essential whitespace may not be preserved by the execution engine for strings inside clown hats.

somecode = <|
var e = 5;
var f = e + 6;
|>;
