I am reading the dip documentation at http://www.riverbankcomputing.co.uk/static/Docs/dip/complete_example.html , and have a question about the following:
"dip will invoke an observe() handler when the value of an attribute is set, even if the new value is the same as the old one. We therefore use the _propagate_changes attribute to prevent possible recursion problems" Why is it necessary to invoke the observe handler when the value of an attribute does not change? There are quite a few infinite-recursion workarounds in the example. If the possibility of infinite recursion is so high, perhaps by default the handler should not be invoked if the attribute value does not change, unless observe() was called with a kwarg to invoke the handler regardless?
