Is writeln even platform agnostic? I've used targets where it 
doesn't do anything.... including Microsoft Windows with the gui 
subsystem.

Generally, I think it is a mistake to reject something that is 
good for a great many users just because it isn't available 
everywhere. If it isn't right for your target, just don't use it.

I would caution against requiring the support libs in Phobos; we 
don't want programs to fail to start because Xlib isn't 
installed, for example. But there's ways to do that.

Any call to a create window function might fail at runtime, on a 
platform with no graphics support, all window creation can throw 
an exception. On a platform with just one screen, any beyond the 
first might throw.

A gui toolkit would probably need to do something about that to 
keep things like pop-up message and dialog boxes working, but for 
the basic stuff just saying it might throw should be good enough.
