I don't think it's that simple. What happens if an XException causes
another XException and they need to be chained together?
If both are thread-local and cached I see no problem whatsoever.
The thing is the current "default" of creating exception is AWFUL.
And D stands for sane defaults and the simple path being good last time
I checked.
