The docs for std.container suggest I should be able to do this:
import std.container;
void main()
{
   auto list = DList!int([1,2,3,4,5]);
   list.front = 3;
}
But this does not compile (not a property list.front). I can't 
figure out why this doesn't work though - the source for struct 
DList(T) contains this:
static if(isAssignable!(T,T))
{
    property void front(T value)
   {
     assert(!empty, "DList.front: List is empty");
     move(value, _first._payload);
   }
}
but that does not seem to be getting compiled in.

What version of Phobos are you using? The source code of Phobos that 
comes with dmd 2.060 does not have the definition that you have shown.
In any case, according to the docs, it is SList that allows setting the 
front element, not DList:
import std.container;
void main()
{
   auto list = SList!int([1,2,3,4,5]);
   list.front = 3;
}

Ah you're right, I was looking at my git head version, which I 
don't use when I build dmd head. So the functionality is there 
already. Thanks!
