Re: how to skip the next (n) item & continue from (n+1) with a range ? e.g. in File(fn).byLine();

Hi,

I need this logic:

```
auto range = File(fn).byLine();
foreach (line; range) {
   if (comeCond(line)) {
      // skip the next n line
      // and continue the foreach loop from the (n+1) line
   } else {
      regularProcess(line);
   }
}
```

Is it possible to do this in a foreach loop?

I wouldn't recommend it, instead do a while loop:

auto range = File(fn).byLine;

while(!range.empty)
{
   auto line = range.front;
   if(someCond(line)) {
        range.popFrontN(n);
   } else {
        regularProcess(line);
        range.popFront;
   }
}
