LINQ is the only thing c# has the is a notable language feature, but I don't 
think it adds anything that puts it much above the rest of the crowd in any 
way.

I think this will work:

int delegate(int delegate(ref T)) Where(T[] array, bool delegate(T) dg)
{
    struct Ret
    {
        T[] Array;
        bool delegate(T) Dg;

        int opApply(int delegate(ref T) idg)
        {
            foreach(ref T t; Array)
               if(Dg(t)) if(int ret = idg) return ret;
            return ret;
        }
        return &(Ret(array,dg)).opApply;
    }
}

If not, a little tweeking shloudl cover it.

There is a lib I played around with a whole back that showed that D can do 
AST manipulation with expressions.

I do  to, but mostly because of the tools
