```d
import std.container : DList;
import std.algorithm : find;
import std.range : take;
import std.stdio : writeln;
import std.range : take;
struct Job
{
     int id;
}
int main(string[] args)
{
     auto list = DList!Job(Job(1), Job(2), Job(3));
     int idToDelete = 2;
     auto toRemove = list[].find!(job => job.id == 
idToDelete).take(1);
     if (!toRemove.empty)
         list.linearRemove(toRemove);

     foreach (i; list[])
     {
         writeln(i);
     }

     return 0;
}
```
works for me ... see https://run.dlang.io/is/OtX820 for a live
