So can I ever get at $seq[3][2]() ?

(1,2,(function(),function()),5,6)

The piece if information you are missing is that sequences dont nest.
They flatten.
(1,2,3) == (1,(2,3)) == (1,((2),(3)) ...
No such thing as sequences inside a sequence (unlike what you might expect if you thought of them as arrays.

So
let $a := (1,2,(function(),function()),5,6) ==

(1,2,function(),function(),5,6)

{( assuming you mean a full function declaration )}

$a[3] == function() ...
$a[3][2] == ()

For something like that, your best bet would be Arrays which are
coming in XQuery 3.1 (most likely).

For the time being you could use maps of sequences, or there are
tricks you can do with sequences of functions and even maps of
functions, or if you really want fun, then just functions of functions
of functions of...

However if you don't want to loose your mind and you can get away with
it, then I would just create an XML representation of an array, and a
module of functions to manage update, insert, delete etc.

Chris,

If really needed, some of us already coded containers mimicking arrays with
XQUERY3.0 (i.e. they would answer 7 to your question).
The bad point is that, would you need them for intensive computing, then I
would advise to wait XQUERY 3.1, because these containers suffers from
performance issues for algebraic operations, an inherent problem to XQUERY
3.0.

Hope this helps

I think, this is sequence of 7 items. As far as I can recall, the internal
sequence (4,5,6) won't be expanded to get the size of outer sequence and
would contribute one item to this result.

you're right. The answer to this question is 9.

I've checked with two XPath 2.0 (i'm assuming XQuery 1.0) processors, and
this answer is correct.
