Thats your opinion. Seeing the boring internals of walking a list a billion times only pisses me off. I rather hide it where it cant be seen and focus on the usefull code instead.
Not macroized into a single unmaintainable ..thing.
There really is no way of "maintaining" how to walk a list. This is pretty much established "science". That why a macro is nice, because i dont want you to see it nor maintain it (or comment on the basic operations of list walking);-P
