I understand this point. From another side, it could be used to write
complex algorithmic : I found this language very handy to that purpose,
because it is a functional language, it is incredibly data flexible, and
template programming is straightforward. Provided basic containers were
added, the community could enrich this language with external modules,
best among them could in turn feed the standardization process. At
present time, as far as I understand, the only way to write a serious
algorithm is to bind XQUERY with an external imperative language, that
is not really a good solution.
You can create a simple linked list using a cons cell:
declare function local:cons($head,$tail)
{
function() { $head, $tail }
};
declare function local:to-list($seq)
{
if(empty($seq)) then () else
local:cons(head($seq),local:to-list(tail($seq)))
};
