What does the S-exp form buy you here? Most of this is magic constants and register writes, which seem about equally hard to read in any syntax. "No inline asm or linker scripts" is also doing a lot of work when x86::write-cr is basically asm with parens and image/section are basically a linker script.

Compiler pass control seems like the interesting part, but why does that imply ALGOL-family languages will be obsolete in 3-5 years? Lisp has had 60+ years to take over. What changes now?
