What do you want to change?

Go 1.22 includes a generic Null type.

type Null[T [any](https://pkg.go.dev/builtin#any)] struct {
	V     T
	Valid [bool](https://pkg.go.dev/builtin#bool)
}

Null represents a value that may be null. Null implements the Scanner interface so it can be used as a scan destination:

var s Null[string]
err := db.QueryRow("SELECT name FROM foo WHERE id=?", id).Scan(&s)
...
if s.Valid {
   // use s.V
} else {
   // NULL value
}

This would make our lives much easier when generating code
