i've read the contributing rules, i decided to go further fixing it, as i found it already marked as a bug, and it's such a great feature to be fixed. i hope it helps, and i hope i'm not violating the rules.

@iifawzi This doesn't work with refs.

Not sure how others would like it, but I'd do something like the object type. Instead of automatically filling default values, you need to explicitly call default() on the array schema to trigger this process. This offers more flexibility imo.

@iifawzi
To sum up, here are a few areas of improvement:

• Have 2 separate loops, 1 for filling errors and 1 for filling default values (keep the current fillOrderedErrors function)
• Retain item order even if we have to generate sparse arrays. Ignore trailing undefineds. A few example outputs:

[1, 2]; // OK
[1, undefined, 2]; // OK (although empty slots are more preferable than undefineds, if an item is undefined just increase the insert pointer i)
[1, undefined, 2, undefined]; // Not OK -> [1, undefined, 2] instead
[undefined, 1, 2] // OK

The best way to implement this, as I said, would be to loop the schemas reversely, and discard any undefineds before an actual value is encountered.

• Tests (normal values, references, templates, nested objects, nested arrays, trailing sparsed items, etc.)
• (Not entirely sure about this) Call state.localize() with path and ancestors and pass this localised state instead of raw state to $_validate() so references and links are resolved correctly. Refer to how ordered schemas are validated within the same file.

Also cc @hueniverse for validation and approval.

Great, this's clear now. I will commit the changes tomorrow night, as it's 3 AM here (GMT+2), thanks @brianle1301 for your valuable time, and for summing this up.

Hi, @brianle1301, i've made all mentioned points, added more tests, it seems much better now, dynamic schemas are resolved, a separate loop is used. i hope we're covering all cases now, waiting for your review.

@hueniverse, When you got a time to check, Is it looks good? awaiting for your review.

@iifawzi Can you please mark all the previous reviews as resolved? Just to clean things up a bit
