-class recursive:
-    '''
-    A decorator class for recursive nested functions.
-    Naive recursive nested functions hold a reference to themselves:
-
-    def outer(*args):
-        def stringify_leaky(arg0, *arg1):
-            if len(arg1) > 0:
-                return stringify_leaky(*arg1)  # <- HERE
-            return str(arg0)
-        stringify_leaky(*args)
-
-    This design pattern creates a reference cycle that is difficult for a
-    garbage collector to resolve. The decorator class prevents the
-    cycle by passing the nested function in as an argument `self`:
-
-    def outer(*args):
-        @recursive
-        def stringify(self, arg0, *arg1):
-            if len(arg1) > 0:
-                return self(*arg1)
-            return str(arg0)
-        stringify(*args)
-
-    '''
-    def __init__(self, func):
-        self.func = func
-    def __call__(self, *args, **kwargs):
-        return self.func(self, *args, **kwargs)
