Nice. Yeah, I would have been surprised if I was the first person 
to notice it, since it is frankly pretty obvious (and happens 
even with hand-written things from time to time, and was a big 
issue with dpp, so not even new).

I didn't see that bug though maybe I'll edit the post to put in a 
link. Walter going "WONTFIX" is pretty much expected though, 
sadly.
