What I actually dream of in a web language (or any language, for that matter) is quite a bit more. I want to be able to get event-driven IO without writing event-driven code. I want to get parallelism for free or as easily as possible. I want to encourage smaller functions and reduced coupling. I want good, or at least decent, performance with no especial effort. I want a consistent and elegant underlying design rather than an ad-hoc collection of features somebody thought were useful.
Ultimately, I want a high-level, modern language that's concise, fast to write, easy to maintain and reasonably performant. And PHP is none of those things. Which is why it's no good.
