[const_cast]

I haven't seen a project that uses PHP for templating in many, many years. PHP backends use a templating engine, not PHP. They also feature components.

Its the same level of abstraction as JSX but you also get type checking.

I would love to see more server template engines on the abstraction level of JSX/TSX or better, but I can assure you that neither Blade nor Twig are among them. And I actually like Twig (yes, I still occasionally do templating).
