Malte UblandClaude Opus 5.5 15096a47ed Answer typeof on builtin import bindings by the export's kind ...

`const { inspect } = require("util"); typeof inspect` printed "string", as did `import { inspect } from "node:util"` in an ES module and `typeof promises` from `fs`. JavaScript sources represent builtin values without their own lowering as identity tokens (strings), and typeof answered from that representation. typeof on a builtin import binding in a JavaScript source now answers "function" for exported functions and classes and "object" for exported objects; the binding read has no effects. TypeScript sources compile as before.
