Firefox 3.5 changes some NodeList functionality

This might not be classified as a bug, but it seems like it. In Firefox < 3.5, a NodeList? returned from dojo.query() had all of the functions associated with a normal array, including Array.push, pop, shift, and unshift.

In FF 3.5, this appears have changed. Now a NodeList? can still be read like an Array, but you can no longer modify its contents. Since length is read-only, you can't even hack the change in.

(I had used this on a website that needed to manipulate a set of links, one of which was in a different location. I simply pushed the odd one into the first query's NodeList?.)


var nodes = dojo.query('a');
var other_nodes = dojo.query('p');
nodes.push(other_nodes[0]); // error occurs here

This wouldn't bother me except it works in every other browser I checked, including IE 6, 7 and 8; Opera 9; and Safari 4. I'm guessing FF 3.5 is now using some internal NodeList? method that is returning a specialized array.

If nothing else, a note might need to be made in the docs about this.
