I think the missing "reset($arr)" has nothing to say in such cases - it 
simply might have been forgotten, although we can't be sure actually. I 
think it's good that the while(list()) stuff got replaced, as the code 
is also better to read not having to track down possible code that's 
changing the array pointers.
