Usage

object: <object name>
{
    member = default_value;
    
    construct = function(...)
    end;
    
    destruct = function(...)
    end;
    
    <et cetera>
}

local instance = new: <object name>(...)
print(typeof(instance))
instance.method(...)
event: update() -- calls update method on all instances that have it
delete(instance)

An object cannot contain a member named "self".

Usage of self. inside a member function is not necessary, as you can access the member directly, without using "self".

However, you can optionally use it anyway, because self is automatically assigned to the instance.
