Stage breakdown for Class Inheritance

1. Class Hierarchy
   • Basic subclass
   • Super and sub classes inside local scope
   • parent in global, child in local
   • cycle: class Oops < Oops {}
   • parent is not a class
     • not callable
     • callable
2. Inheriting methods
   • check type of subclass
   • function which expects super should accept sub not statically typed can't check
   • access inherited fields
     • non callable
     • callable
3. Super keyword
   • super.method()
   • sub class method with same name gets precedence (overriding)
   • super should return 1st class function
   • super should be called from superclass ;)
4. Invalid usages of super keyword
   • call super.func() from a class with no superclass
   • super.func() outside
   • can't have bare super - without class - also without . & prop
5. Misc Error handling
   • inherit constructors
   • Var resolving
     • class.cook
     • super.cook
     • this.cook
