And NamesTuple was designed to BE tuples -- that is a drop in replacement for tuples -- so they have the features they have partially for that reason. And my toy code actually adds another decorator to make dataclasses iterable, so it would be a completely optional feature. All that being said, I'm not actually advocating doing this with dataclasses -- I'm simply making the point that there are currretly two ways to make custom class able to be passed in to the dict constructor -- do we need another? -CHB -- Christopher Barker, PhD Python Language Consulting - Teaching - Scientific Software Development - Desktop GUI and Web Development - wxPython, numpy, scipy, Cython
