Hi,
some simple leads,
Use one line initialization of Person
p := &Person{Attr:&Attribute{}}
Enhance the if conditions statement
if p.Attr != nil && p.Attr.Age < 10 {
fmt.Println("Too Young")
}
Use a Person constructor
func NewPerson() &Person {
return &Person{Attr:&Attribute{}}
}
I, too, dislike that default values for struct pointer properties is nil.
