Is there a nice syntax to achieve optional named parameters?

[John Burton]

As an example let's say I have a type 'Window' that represents a 
win32 window. I'd like to be able to construct an instance of the 
type with some optional parameters that default to some 
reasonable settings and create the underlying win32 window.

I'd ideally like some syntax like this :-

auto window = Window(title = "My Window", width = 1000, 
fullscreen = true);

Assume that title, width, fullscreen are optional and if not 
specified there are defaults to use. And that there are many 
other settings than just these 3 that I've chosen to just use the 
default here.

I know that I can't do it like this is D but what is the best way 
to achieve this kind of thing? I can add properties and then do a 
specific "create" function to create the underlying win32 window 
once I'm done but that seems ugly.

auto window = Window();
window.title = "My Window";
window.width = 1000;
window.create();

This is ok, but I'm not so keen on separating the creation and 
construction like this.
Is there a better way that's not ugly?
