There was a problem hiding this comment.
Oh no, this means that CJS isn't even erasable because we assume strict and always insert it

Per discussion; this syntax isn't supported by Node.js/Amaro or
ts-blank-space, andexport=is not actually erasable as its transformed syntax ismodule.exports=.This effectively means you can't write any CJS code under
erasableSyntaxOnly(without usingconst foo = require("foo")andmodule.exports = ...directly, which do not bind in TS). Perhaps we can makeconst foo = require("...")andmodule.exports = ...bind like they do in JS for TS files in the future.Updates #59601
