What are you trying to accomplish?


T

actually i just want to do some commandline parsing with default-values  
like this:
int main(string[] args) {
   auto h = [1, 2, 3];
   if (args.length > 1) {
     h = iota(1, args[1].to!(int));
   }
   do_something_with(h);
   return 0;
}

In that case, you should probably replace
  h = iota(1, args[1].to!(int));
with
  h = iota(1, args[1].to!(int)).array();
(assuming 2.059)
or
  h = array(iota(1, args[1].to!(int)));
