So, er.... I feel in the "target market" of this DIP, we use 
D-with-runtime-disabled
and the codebase is completely @nogc.
The DIP is not that appealing to me because we do manage to 
throw/catch anyway with manually allocated exceptions.

So most likely I would put this attribute in the "do not use" 
list of D features.

I'd be more excited about:
- throw-by-value exceptions
- a way to use exceptions in @nogc and even -betterC (There was a 
DIP for it, it was implemented, but doesn't work IIRC)
than improving error codes.

That said, I have no real idea how much needed this DIP is.
