`!retsam19:screenshot`:

Rather than screenshots, please provide either code formatted as:

```ts
// code here
```
Or even better, as an example on the Typescript playground https://www.typescriptlang.org/play that is as simple as possible and reproduces the issue. This makes it easier to help you and increases the chances of getting an answer.

You can use satisfies and change it slightly:

coarse sequoiaBOT
# 
type A<T> = {
    b: T
    c: (d: T) => void
}

const a = {
    b: 'a',
    c: (d) => {},
//      ^? - (parameter) d: "a"
} satisfies A<'a'> | A<'b'> | A<'c'>
