E0111: missing body for class
Classes require a body, which must be a list of properties and methods
surrounded by { and }. It is a syntax error to omit the body of a class:
class Animal {}
class Doge extends Animal
class Kitty extends Animal
To fix this error, write the body of the class, including { and }:
class Animal {}
class Doge extends Animal {}
class Kitty extends Animal {}
