  // +   original by: Brett Zamir (http://brett-zamir.me)
  // +    depends on: class_exists
  // *     example 1: function A (z) {this.z=z} // Assign 'this' in constructor, making it class-like

### Example 1
This code
{% codeblock lang:js example %}
function A (z) {this.z=z} // Assign 'this' in constructor, making it class-like
function B () {}
B.c = function () {}; // Add a static method, making it class-like
function C () {}
C.prototype.z = function () {}; // Add to prototype, making it behave as a "class"
get_declared_classes()
{% endcodeblock %}

Should return
{% codeblock lang:js returns %}
[C, B, A]
{% endcodeblock %}
