This assumption is violated by several very common idioms, such as the header-footer idiom in ways that often require drastic changes to repair. Similarly, structured programming makes assumptions that are violated by common idioms such as unrestricted GOTO statements jumping all across your tangled spaghetti code. Maybe the header-footer idiom is not a good idiom.
