Remove element from DList

[cal]

I'd like to remove a single element from a std.container.DList. 
For that I need a range, but I'm not sure how to get a single 
element 'range'.

I thought something like this might work:
auto list = DList!int([1,2,3,4]);
auto r = list[];
while(r.front != 3)
   r.popFront;

list.remove(r.take(1));

But the the range returned by r.take(1) is not valid as an 
argument to DList.remove. What is the correct way to do this?
