[Cython] transform efficiency

[Dag Sverre Seljebotn]

(answering the question below, sorry about top-post (on cellphone)):

You do something like this:

classname = None
def visit_ClassDefNode(self, node):
    oldname = self.classname
    self.classname = node.X # name?
    # or perhaps node.entry.name
    self.visitchildren(node)
    self.classname = oldname

def visit_FuncDefNode(self, node):
    ....
    use self.classname
    ....
