Now if you think about it, PJAX sounds a lot like Turbolinks. They both use JS to fetch server-rendered HTML and put it into the DOM. They both do caching and manage the forward and back buttons. It's almost as if the Rails team took a technique developed elsewhere and just rebranded it.

I'm suggesting there should be a way to write lifecycle related code that also responds to changing props, like how useEffect works. I think how React handles this could be a good source of inspiration.

one that would borrow the best features from the ABC language
