Form Validation of array variables and form_error() and set_value()

This is more of information post, so others can benefit from my toils...

Ok, I was able to dig down to the root cause of this error.
If I submit a POST array like this:

Code:

<input name="var1[]" value="something" />
<input name="var1[]" value="" />

and apply the following form validation rules:

Code:

trim|max_length[255]|alpha_numeric

The second value in the array will fail validation even though its not required as defined in the rule list.

Additionally, form_error() only stores a single error message, which prevents the user from properly identifying which index in the array is erroneous.

Finally, set_value() returns a single value, requiring me to use a while loop to extract all of the values. The forums indicate they may return an array. Can anyone confirm this is for CI2.x?
