Why would it be "very, very wrong"? Perpetual cycles are

Hum... you guys seem to be forgetting about break statements.

You know when you want to do something, and also do something 
*between* each iteration, but don't want to check your end 
condition twice per loop? It usually ends up looking something 
like this:

T[] arr = ... ;
auto len = arr.length;
write("[");
if ( len != 0 ) {
  size_t i = 0
  for ( ;  ;  ) {
    write(arr[i]);
    if (++i == len) break;
    write(", ");
  }
}
write("]");
