Ref. #118977 Please see this issue. It's not fixed. It is marked as duplicate of microsoft/TypeScript#38922. And should have been fixed by microsoft/TypeScript#42364. But it is not fixed. Or am I missing something?

* The best decorator ever made.

* @todo Fix the "@" bug in code block.

* @example
*
* ```ts
* class MyComponent {
* @SomeDecorator() myValue = 42; // <- This is the problem line.
* }
* ```
*/
export function SomeDecorator() {}
