$.extend with modified object prototype

[markQuery]

The code

$.extend( $.ui, {

$.ui.plugin is deprecated. Use the proxy pattern instead. plugin: {

add: function( module, option, set ) {

var proto = $.ui[ module ].prototype; for ( var i in set ) {

Is using the for...in syntax. If the prototype of the Javascript object has been extended this breaks. Instead it should probably use for ( var j = 0; j < set.length; ++j )

Sorry I am not very familiar with Javascript or jQuery so it would be a lot of effort to make a test case. I'm seeing the problem on a private site.

jQuery doesn't support modifying Object.prototype.
