-Starting version 3.9, TypeScript emits module exports using \`Object.defineProperty\`,
-with \`configurable: false\`, instead of \`exports.thing = module.thing;\` as it always used to do.
-This means, that any object mutation after the initial compilation are impossible and makes
-the package slightly less open for modifications, and prevent users from experimenting with it,
-and from implementing some of their scenarios.
-
-If you REALLY know what you are doing, and you REALLY want to use a different version of TypeScript,
-modify \`TYPESCRIPT_VERSION\` constant at the top of this file (\`scripts/verify-packages-versions.js\`).
