Perhaps this is a better channel to ask this question :)

What does that code even do? First, I thought it was invalid, but I see using a Scratch file that it compiles.

BUT I don't see what it does, if anything. In example, stringParam isn't available, so the name doesn't do anything.

At my call site, the first parameter to the Lambda is still called `it`.

Do you see something different?

I suspect what you want is all call sites of `example` to change from

```
example {
    it.subString(1)
}
```

to this automatically?

```
example { stringParam -&gt;
    stringParam.subString(1)
}
```

If that's ultimately what you're after, I'm not aware of a way to automatically do it.

Yes, that's exactly what I am after. The purpose of defining such param names is pure UX. If it's retained in `@Metadata` then IDEs or a lang server can read it out and provide better naming suggestions for auto completion etc.

An interesting idea, and helpful to avoid everything being `it`, and potentially ambiguous.
