I agree that nil is error prone, but I don’t think interfaces add any additional confusion so long as you think of them as a reference type and reason accordingly. Also, I think you’re mistaken about “true nil”. A “true nil” only requires the interface to be nil. The value doesn’t matter as there necessarily is no value (moreover interfaces can have values which are value-types that cannot be nil!). |
