class:create, which allocates a new instance without invoking the class initializer30log-commons.lua
class:cast(), changes the class of an instanceclass:subclasses() returns the list of all classes which extend from class
class:instances(), returns the list of all instances of class
class:classOf(), checks if class is a superclass of argclass:subclassOf(), checks if class is a subclass of arginstance:instanceOf(), checks if instance is an instance of argclass:without() to remove a mixin from a classclass:with(), includes a mixin to a classclass.isClass, now only checks if arg is a classclass.isInstance, now only checks if arg is an instanceclass:include()
class is considered to be the instance of any superclass of class
require "30log" now returns a callable tableclass.isClass
class.isInstance
subclass.super returns the superclass of subclass
instance.class returns the class of instance
class prototype to class(name, params)
class:__init() to class:init()
class.__name to class.name
class:extends() to class:extend
class:is() to class:extends
class:has() to class:includes
class:extend prototype to class:extend(name, params)
tostring(class) and tostring(instance) output.class.is and instance.is to inspect inheritance relationship between two objects.include, not with
new
__tostring output (class (?) instead of class (Unnamed))30logclean (Thanks zorfmorf)__init can either be a table or a function
