Sean Baxter is doing a decent job with his Circle compiler, so I hear. https://www.circle-lang.org/

Unfortunately, we live in the real world where compilers do not do the things that you suggest that they ought to.

I'm not sure what you mean. Are you talking about the benchmarks? I run `cargo clean` before each benchmark. That should clean up changes to third-party crates, right?

I'd love to try Zig and Jai for this purpose, but they are not stable yet. If either becomes stable, I'll happily re-run this experiment. Nim doesn't look like the language for me.…

Good question. The author of Zig claims that dev build times will be amazing. One technique is to avoid LLVM. Another technique is to integrate the linker. But all of that is a wor…

I have found Clang's -ftime-trace flag helpful in finding bloated #include-s and templates. Also, I have analyzed the .ninja_log file (for CMake+Ninja) to find slow-to-compile .cpp…

No, I'll stay far away from them, thanks. ;P

It is a beast. I love my MacBook Pro!

I'd wager that the C++ compiler does more work churning through #include-s than the Rust compiler does tracking borrows.
