Hi all,
   I've found discussions, but not an actual "recommended" solution for
the problem of "statement is not reachable" warnings in templates with
early returns, e.g.:
```
bool nobool(T...)() {
     foreach (i, U; T) {
         static if (is(U == bool)) {
             return false;
         }
     }
     return true;  // emits "Warning: statement is not reachable"
}

Instead of foreach, you could use recursive mechanism. Not ideal, but it 
would work.

Another possibility:

foreach(i, U; T) {
   static if(is(U == bool)) {
       return false;
   } else static if(i + 1 == T.length) {
       return true;
   }
}
