It's working like IN over a string, e.g. the [5,61] will make selected
the number 5,6 and 61.

<dtml-call "REQUEST.set('ids_test', '(' + id_test[1:-1] + ')')">

Where id_test is the result of the database query wich return in this
format: {1,2,3}. I modify it to a  (1,2,3) and finally I try the
        <dtml-call "REQUEST.set('list', _.list(ids_test))">

Following this api: 

list (sequence)
    Return a list whose items are the same and in the same order as
sequence's items. If sequence is already a list, a copy is made and
returned, similar to sequence[:]. For instance, list('abc') returns
returns ['a', 'b', 'c'] and list( (1, 2, 3) ) returns [1, 2, 3].

I need a integer-list, is it possible?
