A modern programming language that makes developers happier.

I've seen this pattern cropping up in some compose repos from others... thoughts? At first glance I guess it's kinda clever for trying to get something to launch only once, but it just seems _bad_

```LaunchedEffect(key1 = "launch_once") {
    myViewModel.doSomething()
  }```

It's basically `LaunchedEffect(Unit)`, isn't it?

Any constant will do but `Unit` is more or less what we standardized on. `true` had some support on the team for a while

`LaunchedEffect(Unit)` is meant to look suspicious in the same way `while (true)` looks suspicious. The lack of a "real" key there is supposed to invite closer reading

we've had some discussion around whether this has been effective or if it's just kinda noisy. The discussion it invites I think is sort of anecdata suggesting some positive results

and in the case of the example that started the thread, the key should probably be `myViewModel` :slightly_smiling_face:
