Description

The stylistic config includes thehttps://typescript-eslint.io/rules/consistent-generic-constructors/ rule, which (in it's default configuration) conflicts with the requirements of TS 5.5's newisolatedDeclarations mode.

In isolatedDeclarations mode, the following code is illegal:

export const s = new Set<string>();

giving an error: "Variable must have an explicit type annotation with --isolatedDeclarations."
TypeScript Playground

Whereas in ESLint, the opposite pattern is disallowed by theconsistent-generic-constructors from the stylistic config:

export const s: Set<string> = new Set();

gives a different error: "The generic type arguments should be specified as part of the constructor type arguments."
ESLint Playground

Ideally, users using both the stylistic config and the isolatedDeclartions tsconfig option should have a less frustrating out-of-the-box experience. I think ESLint devs are better positioned to make the call on what that should look like, but I few options that I can think of would be:

1. Turn offconsistent-generic-constructors by default in the stylistic config, or
2. Change the default behavior ofconsistent-generic-constructors to avoid running on isolatedDeclarations projects, or
3. Change the default behavior to distinguish local and exported declarations so it can give errors that don't contradict the isolatedDeclarations ones.
