Have you actually tested the insert (both edge and non) iterators, for 
instance?

Bootstrap with -ftree-pre will tell you if you broke them (PRE isn't on 
by default because of one small bug elsewhere causing it to make one 
elimination in 253.perlbmk's util.c file, causing an infinite loop in 
perlbmk)
