A pile of shit emerging whenever programmers are lazy and try to cut corners or when they try to do things they don't fully understand is not unique to macro writing.
Right, the point i was making is that not everyone is a 'rockstar' and macros just give you quite a bit more rope to hang yourself with. Awful java/python/whatever is obvious because you can't redefine control flow so easily. With macros you can have something as fundamental as loops be broken.
