I've been meaning to ask you what the motivation of your project is? Why would you want a safe-c? When I saw the headline I was worried that all my runtime code would break (or get slower) because I do some very unsafe things (I have a runtime that I compile with -nostdlib)

I'm also tempted to write a commercial C++ compiler, but it feels like a big ask, paying for a compiler sounds ridiculous even if it reduces your compile time by 50x

My motivation is that I love to write compilers

That's the best answer. Just wondering because you have a lot of experience and many people disagree with me.

How realistic is a C++ compiler that's 50x faster than clang for debug builds? Assuming 1) there's enough work for each core 2) there's so many files/headers that a unity build takes 1/4th of the time as a rebuild using individual files (this theoretical compiler would be multi-threaded)
