You are both right.
In principle, you can use "sequence-item" and get the object.
Later, when you use it, you can select whatever you need.
However, you used:
<dtml-call "REQUEST.set('ret', ret + ' ' + _['sequence-item'])">
The "_[...]" calls "...", if this is callable.
Thus, "_['sequence-item']" first returns the object and then
calls it, if this is possible. In case of a DTML method, the
result would be the rendered body of the method.
You can use "_.getitem('sequence-item')" to get the object itself
and not the result of calling it.
