I believe that you'd just do
auto rb = RedBlackTree(4, 1, 2, 3);
The problem with the version in dmd 2.052 though is that you can declare one
if there isn't anything in it. Or at least, if you do, you'll run into
problems, because it won't have been properly initialized (due to the lack of
default constructor).
The version in git (which can be gotten here if you want to try it out:
https://github.com/D-Programming-Language/phobos/ - though given how much
trouble that you've been having getting dmd to work, I'm not sure that you
want to try building druntime and Phobos yourself) changes RedBlackTree to a
class, which fixes the problem. And by adding the function redBlackTree, it
manages to make creating one a lot more flexible. The current version should
work just fine though. It just isn't quite as nice (but the first version of
Phobos with RedBlackTree was either 2.051 or 2.052, so it's a quite recent
addition to std.container).
