@tewha @atomicbird I don’t necessarily consider it a code smell. Many methods are better kept “quasi-atomic”; adding methods just to organize should be weighed against the increased API surface (and dev tendencies to use/reuse/*repurpose* methods inappropriately), as well as whether it improves or reduces testability.

With this, I’d consider adding it to Array<Expense> with a default parameter of `.now` to improve its reusability and testability, but many might feel it reduces discoverability.
