This is your bad assumption.  I can write a sentence that is 12 words 
and 100 characters long, or I can write it using only 6 words that are 
50 characters long.  If those 6 words aren't in common usage, then most 
people won't understand it when they see it, and so it is harder to read 
even though it is shorter.

To show another example in C, I can write:

if( condition1 )
   if( condition2 )
     if( condition 3 )
     else dosomething2();

or I can write code that does the same thing, but is shorter:

condition1 && dosomething1(), condition3 ? dosomething3 : dosomething2();

Yes, the latter code is shorter, but the former is far easier to read 
and maintain.

To try and steer this back to the original issue, the LIST_FOR_EACH 
macro causes nonintuitive branching which is hard to understand when you 
read it, and when working on the code, as Alex said, you often have to 
demacrofy it which can introduce more errors.  These are legitimate down 
sides to using the macro, so again, you need a good reason to use it.

So far you seem to only keep insisting that the macros look better to 
you, so I say again, pleasing your sense of aesthetics does not outweigh 
the loss of maintainability.
