Tough one. I'm not entirely sure that interpreting a hash behind a blessed object is something I want to encourage. I think that once an object has been blessed, one should forget about its implementation.
I'm particularily worried that if one day we want to pass a, say, URI::URL object to the method, I'll have to distinguish between interpreting it as an object or as a blessed hash which I want to interpret as key/value pairs.
Could you work around the problem by having your objects provide a $obj->as_hashref method and using their result for init() ?
