Description

@ifeltsweet
  • I have tried restarting my IDE and the issue persists.
  • I have updated to the latest version of the packages.
  • I have read the FAQ and my problem is not listed.

Repro

{
  "plugins": ["@typescript-eslint"],
  "extends": ["plugin:@typescript-eslint/recommended"],
}
const command = (): ParameterDecorator => {
  return () => {
    //
  };
};

class Foo {
  bar(@command() command: string) {
    //
  }
}

Expected Result

No warning.

Actual Result

Warning on line 1:

'command' is assigned a value but never used. eslint@typescript-eslint/no-unused-vars.

Additional Info

Using different names for decorator and parameter does not produce the warning.
