Hey @andrewbranch, 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/111062/artifacts?artifactName=tgz&fileId=7CA2AC096B167B7FDD4276560CB0C161A854525027E66E66D7D7B6164D844A3102&fileName=/typescript-4.5.0-insiders.20210921.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@4.5.0-pr-45974-3".;

Hey @DanielRosenwasser, 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/120005/artifacts?artifactName=tgz&fileId=EE505446B5807332B826CBF47E7BCADCF9F3437137E46FBD2665ED222C83B2FD02&fileName=/typescript-4.7.0-insiders.20220214.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@4.7.0-pr-45974-15".;

@weswigham @andrewbranch @DanielRosenwasser is this good to go into 4.7? Looks like we've got a recent performance run for it now.

This is something I wanted to figure out - whether the check time increases on the most recent change are within the margin of error.

Between zero and seven hundreths of a second (depending on the test, mapping to between zero and one point four percent) sounds like noise if not noise-adjacent numbers to me.

Yeah, this second run makes it look more like noise. We see check time decrease on some and then increase on the same repo with a different Node version.

From the design meeting:

  1. If you look only at check time, there is a small, consistent increase, about 0.7%.
  2. We are still likely to take this because we believe that computed properties are being used more over time.
  3. Anders wants to take a look at the code before merging.

Weighing in as one user: supporting symbol-named properties in CFA (without temporary variables) seems very nice and is definitely what I would expect. For me, it's easily worth this tiny performance penalty, though I probably like/use symbol named properties more than many.

(happy to move this to a new issue)

If I read the release blog post correctly, the following test case should work, but it still produces an error.

interface Foo {
  [key: string]: number | string;
}

declare function generateKey(): string;

function fn(foo: Foo) {
  const key = generateKey();
  if (typeof foo[key] === 'number') {
    foo[key].toExponential(2);
    // Error: Property 'toExponential' does not exist on type 'string | number'.
  }
}

Is this a bug?

I'd definitely file that as a separate issue, otherwise we're not going to be able to track or discuss it.
