Interpreter and JIT from one implementation
“a better approach to writing interpreters these days, because you get a JIT and lots of language interop for free”
Comment from 22 Oct 2026 in “Tell HN: 2x PHP RCE CVEs with CVSS 10.0 Incoming” “implement the language semantics once and you get both interpreter and JIT safely out of it”
