Code can have ambiguous scope too, except the compiler has a decision making process that you might not fully understand. (Closures are famous for this problem).

Natural language doesn't have such rules. My example above isn't an example of incorrect English, there isn't a correct interpretation. The grammar is correct and both interpretations are correct.
