Musing on the the usefulness of actions that update the database and return something, specifically in a web server with Xforms context, and the absence of XQuery scripting. I have been playing around with things like the following:

let $s:=util:eval('
let $x:=copy $c:=db:open("listman","1.xml")
modify (replace value of node $c/updated with current-dateTime())
return $c
return db:replace("listman","1.xml",$x)
')
return db:open("listman","1.xml")

This works, but is it likely to stop working in the future? Is there a better way?
