Return type of ReflectionClass creation

# Support question

What should I do with `@return` when returning the `\ReflectionClass` of a generic class?

I tried the following:
- `@return \ReflectionClass<Bar>`
- `@return \ReflectionClass<Bar<T>>`
- `@template T` + `@return \ReflectionClass<Bar>`
