LLVM is

  - Slow to compile
  - Breaks compilers/doesn't have a stable ABI
  - Optimizes poorly (at least, worse than GCC)

Mojo... I have things I could say... But I'll stick to this. I talked to engineers there and I asked one how they expected any python developers to use the planned borrow checker. The engineer said "Don't worry about it" ie they didn't have a plan. The nicest thing I can say is they didn't bullshit me 100% of the time when I directly asked a question privately. That's the only nice or neutral thing I could say

As for the header thing, that'd could potentially be true if the compile time was something like 450ms -> 220ms, but why bother saying it when you're only saving a few hundred milliseconds

I can't remember how fast D was but iirc it was fairly fast. Actual fastest is my compiler which I don't work on anymore and isn't ready for production. It's the only compiler I know of that hit millions of lines <1s in a non trivial language https://bolinlang.com/

After writing that, I wrote my own standard library (it has data structs like vector, hashmap and sets; slices, strings, rng, print, some io functions, and more) which uses a lot of templates, and it compiles in <200ms on both clang and gcc. Many standard library headers take much longer to compile than that. It's not a terrible idea to have your own standard lib if you need quick compile times.

You could use io_uring but IMO that API is annoying and I remember hitting limitations. One thing you could do with io_uring is using openat (the op not the syscall) with the dir fd (which you get from the syscall) so you can asynchronously open and read files, however, you couldn't open directories for some reason. There's a chance I may be remembering wrong

I have had several projects where I didn't want to be forked, especially by a company with a marketing budget. I choose not to distribute it with an open source license. There's nothing wrong with that. Companies have sold copies of source to people who paid, so that's an option. But I don't know of any licenses like that which have been written for the public to use (copying a company license is a copyright violation)

I feel like this article is the equivalent 16 paragraph stating you're likely to be correct only 10% of the time when you guess a random number from 1 to 10

I wrote a compiler/language, and I was expecting something different from the article after my experiences

Like many of the other commenters, I didn't like the article
