Still, by the time your compile times are getting longer but are still tolerable, you can investigate and stop generating further template bloat. The compile times don't jump from 3 sec to a minute overnight, unless it's something that can be fixed easily.

Of course, if the problem of the blog poster is having continued to soldier on with compile-time format or regexp or similar, then there might not be an easy fix. Still easier than switching language though.

Update: Correction! I've benchmarked it and this surprisingly appears to not actually make much difference. A lot of it seems to be going to boilerplate, unsurprisingly.

I wish `-vtemplates` gave you sum compiler time spent per template.

Hi all. I came across this article on Hacker News: https://www.yet-another-blog.com/porting_the_game_to_jai_part0/

I’m interested in reading your thoughts on the ‘Why not D’ section. Anyone have experiences that match the specific points there? I haven’t experienced them but I also don’t debug on Windows. I also find D’s documentation to be excellent.

I’m super-positive on D but also interested in whether there are others with the same issues as the article’s author.

Thanks everyone for the replies. The context they provided was a great compliment to the article. There are some good learnings here too.
