{{ puts "foobar" }}
Another one would be zig via comptime, but never tried that.
Good to know... doesn't sound like it's some kind of standard
"2021" feature, though. Those are all lesser-known languages
(like D), not industry standard stuff like C++, Java, etc.

Dlang still doesn't have ctfe write functions? Yes.(afaik) It has shot me on the foot once, to the point i abandoned the idea of ever accomplishing what i wanted to do at compile-time and instead just did it at module construction-time, and i must admit that it was immediately easier to debug.
