even when you index beyond the bounds of the slice?

you may not actually be reading memory because it's zero length, but 
it's still logically invalid; you've gone outside the valid range.

in vc9, if you increment an iterator beyond the valid range you get a 
debug assert. that's caught quite a few bugs where I work when we 
upgraded to vc9.
