My application is a graphical game. I close stdout and stderr
by passing `-subsystem:windows` to `lld-link` to suppress the

resources, can't open display, ...), I throw exceptions, log
them to logfile, then re-throw them to crash. I can tell
Windows users to look in the logfile, but it would be more
fitting on Windows to show an error dialog box in addition to
the logging.
```d
int realMain(string[] args)
{
// all your normal code goes here
}
int main(string[] args)
{
version(Windows) {
try {
realMain(args);
} catch(Exception e) {
visualDisplayOfException(e);
throw e;
}
} else {
// presumably, non-windows systems shouldn't show a
graphical Exception
// trace?
realMain(args);
}
}
