DList seems to have an issue with remove:

auto list = DList!int([1, 2, 4, 6]);
auto res = find(list[], 2);
list.remove(res); //ok

Are there any known workarounds besides linearRemove?
There is (unfortunatly) no support for takeOne in DList.
However, "linearRemove" is not a workaround or worst than remove.
It is just that it accepts a wider range of input, when O(1)
cannot be guaranteed. If you are operating with a range of length
1, then linearRemove is still O(1).
