It doesn't matter, if it's returning that value and you're not setting variables to it, you're not creating a reference to it or any form of a leak.
I'm not exactly sure what you are trying to accomplish here. There's nothing wrong with just doing call CreateItem.... or anything of the sort. Locations, Groups, Timers, etc are different, as there are no functions to call these types back out of the memory. Units, items, etc have ways of getting these objects in case you need to destroy them.
I do know this - xenforo dropped the ball by not keeping the vbulletin reputation comments as a feature. The loss of the Reputation comments data when we switched to Xenforo really was the death knell for the site when it came to all the users that left. I know I missed it so much and I got way less interested in the site when that feature was gone and I run the site.
I'm on a page about incorrect corrections, and spent the better part of like two hours trying to get someone to understand that -5^2 = -25, not 25, and then that post had comments get reposted because that group is self sustaining, and that person was in turn trying to explain what I just explained to them. And I'm taking that as a victory
