Well, do loops are the least frequently used looping constructs. Also, 
if you actually have code like the following

import foo; // defines global symbol 'x'

void main(){
     do {
         int x;
         // ...

It is likely that it is actually buggy because the programmer assumed 
lookup would work differently.
