### Example 1
This code
{% codeblock lang:js example %}
var A = function () {};
A.prop = 5;
A.prototype.someMethod = function () {};
var b = {};
aggregate(b, 'A');
aggregate_info(b);
{% endcodeblock %}

Should return
{% codeblock lang:js returns %}
{'A':{methods:['someMethod'], properties:['prop']}}
{% endcodeblock %}
