Hey @gabritto, the results of running the DT tests are ready.

Everything looks the same!

You can check the log here.

Hey @gabritto, I've packed this into an installable tgz. You can install it for testing by referencing it in your package.json like so:

{
    "devDependencies": {
        "typescript": "https://typescript.visualstudio.com/cf7ac146-d525-443c-b23c-0d58337efebc/_apis/build/builds/161979/artifacts?artifactName=tgz&fileId=1BFA18BBC6DA0A2A9A0BB31A899B882DF274F7A83CD3BA53C4D866A4F3E3280A02&fileName=/typescript-5.5.0-insiders.20240529.tgz"
    }
}

and then running npm install.

There is also a playground for this build and an npm module you can use via "typescript": "npm:@typescript-deploys/pr-build@5.5.0-pr-58702-7".;

I'd add an extra test case to the original test file here based on Anders' comment in the other PR:

declare function bar<T extends string>(x: `${T}`): T; function baz<U extends string>(x: `${U}`) { return bar(x); }

Andarist · 2024-05-30T08:17:20Z

+!!! error TS2322:         Type '"a"' is not assignable to type '`${T2}`'.
+
+    function f3<T3 extends "a" | "b">(x: T3) {
+        const test1: `${T3}` = x    


it could be nice to add comments to both of those assignments to explain the error, like:
