Hey @weswigham, 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/149553/artifacts?artifactName=tgz&fileId=BF97D3A2ED3794BA1156A36EB43AF5F3D6738F0DED63E272F016EDB4676E4E4102&fileName=/typescript-5.1.0-insiders.20230315.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@5.1.0-pr-52609-5".;

Weird that doing inference on a non-context-sensitive function helps here, but I guess it makes sense since it's a contravariant inference anyway. Makes me wonder if we shouldn't just always be inferring from annotated parameters in inferential contexts, though that's a lot more work, generally. Tests all look OK, so I guess I'll merge this~
