Somebody on the C++ side has written a reply....


Although looking at the implementation of std::conditional in the 
type_traits header makes me sad...

I would love to see the whole checkedint thing in C++ side by 
side with the d code (and generated -Os object code).

Conversely I'd love to see a Rust implementation too :-)

Given that I have probably written a lot more C++ code in my life 
than d...

...I do find it remarkable that I can read the d code quite 
easily without reaching for the reference manual, but to make 
sense of his C++, it sends me trawling around cppreference.com

I find Andrei's claim that checkint with a void hook reverts to 
int is amazing, and would love to verify that at the assembly 
level for both the C++ and d implementations.
