// Example:
//
// type Config struct {
// // This field must be set to a non-nil value,
// // forcing the caller to make their mind up
// // about this field.
// CriticalSetting *nodefault.Bool
// }
// type Config struct {
// // This field must be set to a non-nil value,
// // forcing the caller to make their mind up
// // about this field.
// CriticalSetting *nodefault.Bool
// }
//
// An function that takes such a Config should _not_ check for nil-ness:
// and instead unconditionally dereference:
//
// func f(c Config) {
// if (c.CriticalSetting) { }
// }
// func f(c Config) {
// if (c.CriticalSetting) { }
// }
//
// If the caller of f forgot to specify the .CriticalSetting
// field, the Go runtime will issue a nil-pointer deref panic
// and it'll be clear that the caller did not read the docs of Config.
//
// f(Config{}) // crashes
//
// f Config{ CriticalSetting: &nodefault.Bool{B: false}} // doesn't crash
// f(Config{}) // crashes
//
// f Config{ CriticalSetting: &nodefault.Bool{B: false}} // doesn't crash
