Additional Comments

Angular introduced new control flow, which works in html templates: https://angular.dev/guide/templates/control-flow and
It would be great if pug could support it, with proper syntax highliting in IntelliJ (that part is perhaps on IntelliJ side, but pug needs to support the syntax first).

It would be really good to have this, we also want to use control flow statements but are blocked by pug.
