With all due respect I disagree with DJB here. I can't see how his proposal would significantly improve the current status quo. Note step one of his self-described "straightforward" transition plan (emphasis mine): >0123456789abcdef0123456789abcdef to 192.5.6.30: The client sends a UDP packet to the .com DNS server asking for the address of www.google.com. The client software, intermediate computers, and server software have all been upgraded to handle the client's extended address. A lot of work in this one "straightforward" step. I know that DJB is a great network engineer, so I'm willing to consider that I'm missing the point here, but at the very least I don't find this particular exposé very convincing. >If we take this black and white approach then we must say that C++ is not C compatible just like Ada isn't C compatible. Agreed, in a parent comment I mention C++ being effectively mostly compatible with C. But I can't really imagine how you could do something like that with a memory-safe subset of C. The changes involved are pretty thorough (you basically either need a garbage collector or a borrow checker). Things like raw pointers (especially nullable ones) can't really exist in their current form in a memory safe language.
