I agree. At least in the jsonify case a "jsonify_explicit" function is added to operate on objects the have a __json__ method, therefore allowing both approaches: Add a rule to jsonify or provide a __json__ method in your objects. Unfortunately, I cannot think of a way to offer this flexibility in other "generic"alized parts of TG like errorhandling.py or the new "expose" (which I admit not understanding yet how it actually works or what advantages it offers :/). On the other hand, error_handler() doesn't need generic function awareness in it's simplest and most common cases, only when doing something fancy which in that case you can provide an optional "rule" parameter. > Some clashes might happen on unexpected areas and they will happen > but hey! > We're working to get it better everyday, right? :-) > > We have the knife and the cheese...
