assuming your expression leads to the name of the object you want 
to add a folder, you could use:

<dtml-call "_[expres].manage_addFolder('new_folder')">

(this is not so simple, if your expres contains or evaulates to
something
with . (periods) in it. Then you would have to split or look along the
mailinglist, there was mentioned something like "get object from url"
