Repro Code

declarefunctionf(...a:number[]):void;declarefunctionf(...a:string[]):void;declarefunctiong(...a:number[]):void;declarefunctiong(...b:string[]):void;

ESLint Config

module.exports={"rules":{"@typescript-eslint/unified-signatures":["error",{"ignoreDifferentlyNamedParameters":true}]}}

tsconfig

{"compilerOptions": {"strictNullChecks":true  }}

Expected Result

Inunified-signatures' document:

// "@typescript-eslint/unified-signatures": ["error", { "ignoreDifferentlyNamedParameters": true }]// Incorrectfunctionf(...a:number[]):void;functionf(...b:string[]):void;// Correctfunctionf(...a:number[]):void;functionf(...a:string[]):void;

In my opinion the document is also wrong. The first one with different name should be correct, and the second one with the same name should be incorrect.

Actual Result

No error is given, no matterignoreDifferentlyNamedParameters istrue orfalse.
