d S )�TransformVisitoraP A visitor for handling transforms.
The standard approach of using it is to call
:meth:`~visit` with an *astroid* module and the class
will take care of the rest, walking the tree and running the
transforms for each encountered node.
Based on its usage in AstroidManager.brain, it should not be reinstantiated.

when called with the node as argument.
The transform function may return a value which is then used to
substitute the original node in the tree.
