Description:
 def LAMBDA(self, node):
 """This is likely very brittle, currently works for pyflakes 1.3.0. Deferring annotation handling depends on the fact that during calls to LAMBDA visiting the function's body is already deferred and the only eager calls to `handleNode` are for annotations. """

        super().LAMBDA(node)
        self.handleNode, self.deferHandleNode = self.deferHandleNode, self.handleNode
