> Panic: call of reflect.Value.IsZero on zero Value
And the "cool" stuff like database/sql's plethora of Null* for every single type it can support. So you're not really avoiding "wrapping values in Option types", you're instead copy/pasting ad-hoc ones all over, and have to deal with zero values in places where they have no reason to be, forced upon you by the language.
And then of course it looks even worse because... not having universal default values doesn't preclude having opt-in default values. So when that's useful and sensible your type gets a default value, and when it's not it doesn't, and that avoids having to add a check in every single method so your code doesn't go off the rail when it encounters a nonsensical zero value.
