OHHH. Haha I had to read your comment before I understood the title. I knew they were talking about the fork syscall while reading the article, but I still assumed the title referred to "forking the compiler on GitHub, so that they could make it better and send a pull request."
It didn't click that the title was also talking about the fork() syscall. I think it's a pun though: "To try it yourself, check out the dmdforker branch in my dmd GitHub fork."
Double OHHH. Just realized upon reading your comment that I'd read the title/article the same way, and then forgotten. I guess “forking the D compiler” naturally leads to the source-forking context.
I guess I've learned to forget/ignore the titles on hackernews after using them to decide whether to click through, since they so often mess with them.
