Your logic is too illogical. It is the proposal's supporters' responsibility to prove the proposal doesn't do harm. If they are unable to do this, please don't pretend that this has been proven, and please just stop making any arguments. It is not my (and all other Go programmers') responsibility to do this. Here, I just shows the possibility that the proposal will do harm, and help others to find the broken cases easily. However, surely, Go programmers, in their spare time, can help the proposal's supporters to do this. But, again, it is strange that the proposal has been accepted before such attempts are made. :D, so weird. And, please read my tweets, there are several factors which are unrelated to finding broken code. In fact, the change will lead to more error-prone, instead of less error-prone.
