I have got one question. Will it work with auto?
auto stream = MakeOne<FileIn>(fn); // Is auot MakeOne or One?
Sure. It will be MakeOne, but that hardly matters.
{
auto in = MakeOne<FileIn>(GetDataFile("Console.cpp"));
One<Stream> s = pick(in);
while(!s->IsEof())
DDUMP(s->GetLine());
}

Why not make MakeOne function rather than class?
Class seems to be more versatile here - you can use it just like function, but you can declare the variable too.
E.g. you can do this:
One<Stream> OpenFile()
{
MakeOne<FileIn> in;
in->Open("asd");
return in;
}
With "function only" you would have to type a bit more...
