You could wrap the loop in an if clause:

     if (condition) while (true) {
         // ...
     } else {
         // ...
     }

This is the semantics of the else clause of Python for (and while) loops:

bool broken = false;
for (...) {
     if (...) {
         broken = true;
         break;
     }
}
if (!broken) {
  ...
}

I agree with BCS in the bug 2304, I'd like something more semantically descriptive 
instead of just an "else".

True. Python tends to overload its keywords, which leads to weird expression.
Also weird, again using "then":

        try:
            n = 1 + 1
        except Exception, e:
            print ("*error*")
        else:
            print (n)

actually means

        try:
            n = 1 + 1
        then:
            print (n)
        except Exception, e:
            print ("*error*")
