[Python-ideas] Introduce collections.Reiterable

[Neil Girdhar]

That was just for illustration.  Here's the code I just fixed to use
Reiterable:

class Network:
    def update(self, nodes):
        nodes = Reiterable(nodes)
        super().update(self, nodes)
        for node in nodes:
            node.setParent(self)
            node.propertyValuesChanged.connect(self.modelPropertiesChanged)
        self.modelNodesAddedRemoved.emit()
