Another idea that's not supported is the pathological way function scope is interpreted. The two dang functions in the MRDV flow past each other, like a case fall-through [2], but for function scopes. It makes sense artistically in the comic, but I'm not super clear on what it would even mean in terms of a real program.
[2] Only Duff's Device comes to mind here, but I think we're looking at something more pathological with the MRDV
