Will popFront and popBack return the element removed? Usually that is

Great question. In STL they can't because C++ couldn't move values
reliably at the time (C++0X still can't IMHO but that's another
discussion). D would be able to because it has good support for moving.
I just don't want inefficiencies; returning e.g. a large struct will
still involve some memcpying even if costly resources are not
duplicated.
So I'm ambivalent about this.
That would seem like another good use for return type overloading:
void popFront();
ElementType popFront();
Too bad we can't have that.
