Use a closure instead of a thisArg. Signatures accepting a thisArg will be removed in v8.

function filter<T, S extends T, A>(predicate: (
this: A,
value: T,
index: number,
) => value is S, thisArg: A): OperatorFunction<T, S>;
function filter<T, S extends T>(predicate: (value: T, index: number) => value is S): OperatorFunction<T, S>;
function filter<T>(predicate: BooleanConstructor): OperatorFunction<T, TruthyTypesOf<T>>;
function filter<T, A>(predicate: (
this: A,
value: T,
index: number,
