This is invalid, as "remove" is a "O(1)" operation, but removing a Take!Range
is linear operation. So that's an invalid argument.

The correct way to remove a Take!Range, is to use the linear removal function:
linearRemove:

//----
import std.range, std.algorithm, std.container;

void main()
{
    auto list = DList!int([1,2,3,4,5]);
    list.linearRemove(list[].find(3).take(1));
}
//----

Well, that's how it is right now anyways. If/when DList will have deterministic
ownership of its elements, things could change, since it would have to call
destructor on the removed elements...
