[OT] - C++ exceptions are becoming more and more problematic

[StarCanopy]

After having built a result library on top of std.sumtype, and 
used it in some small programs, I have more appreciation for 
exceptions as its interface for error handling effects less 
clutter. And D's implementation could even be improved as shown 
by Adam's efforts and posts in this very thread. (Quite fond of 
rikki's ideas.)
