For loops like this I'd recommend using some kind of FOREACH macro (the 
functional equivalent of BOOST_FOREACH; this is easy to write when you 
can use GCC's typeof feature). I've found that using a FOREACH macro 
improves code readability significantly. Not only is the normal case 
shorter and clearer, but it also means that when you do spell out a for 
loop explicitly, it acts as a signal to the reader that "we're doing 
something more complicated than straightforward iteration here, so read 
carefully".
