While being a very modest piece of code in and of itself, I
believe this offers a significant opportunity that both D
compilers and user defined types can exploit.
Not only can it be used to create an efficient safeint data
type, it can be used to implement multi-precision integer
arithmetic types.
I'd also like to see it used to replace the various ad-hoc
schemes currently in use. It should also be used in dmd itself
for things like detecting array size overflows, which is
currently done ad-hoc, and detecting overflows in CTFE.
