Of course, depending on the container, changing the index may or may not 
make any sense.  Arrays are linear, maps are not.  So if you have a foreach 
loop that could skip elements, it would only be useful on those containers 
where skipping ahead made sense (you lose one element of that agnosticity 
(if that's even a word (which I doubt it is :X ))).

I'd say when you start needing to change the index, use a for loop; that's 
what it's there for.
