Ordered <set of items> have the advantage of working well with the brain's ability to map its surroundings. "function foo is defined 5 arrow downs above function bar". When the <set of items> jump around our eyes in arbitrary order, we tend to experience disorientation.
OTOH I always wonder if it would not be beneficial if our brain and the code would not rely on spacial distances in code files, but on _call_ distances.
Should our spacial map of the code not be the call graph instead of the structure in files and disk?
