GUI and non-GUI stream usage?

Correction: I just realized that dout does *NOT* throw an exception, but 
derr does.  Whether exceptions should be thrown or not, that seems like 
inconsistent behavior to me.

This does seem to work, for anyone who's interested.

version (Windows) {
     std.c.stdio.freopen("Nul", "w", derr.file);
}

And the exceptions go away.


In the bigger picture it would be nice if I could rebind dout and derr 
to a different Stream so that I could write a GUI StreamLogger class. 
 From the rumblings I hear, I'm guessing that sort of thing is probably 
possible in Tango?
