I think the idea here is that you could specify, in your own custom class, which type(s) you can convert to, and it could be any type. That being said, to the OP: what are your use cases here? adding a dunder requires compelling use cases, and in this case, why having a dunder would be more helpful that simply writing a convert to this type method on your class. And when would that dunder be called? I'm having trouble figuring that out. -CHB > See > https://docs.python.org/3/reference/datamodel.html#special-method-names > > Oleg. > -- > Oleg Broytman https://phdru.name/ p...@phdru.name > Programmers don't die, they just GOSUB without RETURN. > _______________________________________________ > Python-ideas mailing list -- python-ideas@python.org > To unsubscribe send an email to python-ideas-le...@python.org > https://mail.python.org/mailman3/lists/python-ideas.python.org/ > Message archived at > https://mail.python.org/archives/list/python-ideas@python.org/message/PTAVFYSXD4KTUYJCBWO7GB7F5QOH6Z5N/ > Code of Conduct: http://python.org/psf/codeofconduct/ > -- Christopher Barker, PhD Python Language Consulting - Teaching - Scientific Software Development - Desktop GUI and Web Development - wxPython, numpy, scipy, Cython
