So interesting to hear about the internals of the browser, how it evolved from a standard library in an OS project. It's the kind of insight that's rarely documented, spoken about, or even known to anybody other than the author.

I can totally imagine how a prolific and ambitious developer would create a world of their own, essentially another language with domain-specific vocabulary and primitives. People often talk about using a "subset of C++" to make it manageable for mortals, and I think the somewhat unusual consideration of Swift was related to this desire for an ergonomic language to express and solve the needs of the project.
