Well, there is yarn and then there is yarn. I don't mean spaghetti code, which is its own problem separate from representation. I'm thinking about interconnection of components, which is fine. Every layer of linux, say, makes calls to the same low level functions. If you tried to draw that it would be unreadable, but it is perfectly fine code - it is okay for everyone to call sqrt (say) because sqrt has no side effects. Well, sqrt is silly, but I don't know the kernel architecture - replace that with virtual memory functions or whatever makes sense.
