I believe instead of a new method, you can add it as a function overload on fromPredicate, like how the types for Array.filter are implemented:

filter<S extends T>(predicate: (value: T, index: number, array: T[]) => value is S, thisArg?: any): S[];
filter(predicate: (value: T, index: number, array: T[]) => unknown, thisArg?: any): T[];
