Removing an element from a DList

[Joakim G. via Digitalmars-d-learn]

For some reason I cannot remove an element from a DList. I tried 
several range approaches but to no avail. I'm a noob.

In the end I did this:
```
private void removeFromWaitingQueue(uint jid) {
    auto arr = waitingQueue[].array;
    arr = arr.remove!(job => job.jid == jid);
    waitingQueue.clear();
    foreach(job; arr) {
        waitingQueue.insertBack(job);
    }
}
```

Any hints?
