This point is what so many miss. The conceptual decomposition seems nice, but the physical implications of that decomposition are horrible. The further you split a function caller from its caller, physically, the more chaos you're asking for. It's quite simple to see from a physical perspective but from an abstract perspective it's all lines and boxes.
