Solve the following python programming problem given the following code:
def _weak_decorator(func) : 
    'Provides a work around for recursive creation of entities in
       an entities constructor. That would otherwise lead to runtime
       exceptions.
    ' 
    def decorator(cls, * args, **kwargs) : 
        result = func (cls, * args, ** kwargs) 
        if isinstance (result, weakref.ref) : 
            return result () 
instanceID = result._instanceID 
        if getattr (result, 'reapable', False) : 
            namespace ['entities'].get (result.__class__.__name__, { 
                
}).pop (instanceID, None) 
else : 
            namespace ['entities'] [result.__class__.__name__].update ({ 
                instanceID : result, 
}) 
cls._instanceMap [instanceID] = weakref.ref (result, (lambda x : cls._weak_callback (instanceID, x))) 
        return cls._instanceMap [result._instanceID] () 
return func
