> dataclasses need to check for ClassVar Interesting, so the use case we are talking about is: 1) You are using annotations to mean actual types, 2) But you also have to inspect them at runtime, 3) For some of the types the name might not be defined at runtime yet
In this example doesn't the current behavior, PEP 649, and PEP 563 (using get_type_hints) all throw an exception? Could PEP 649 be modified to say that if a NameError is raised the result is not cached and therefore you can inspect it later at runtime to get the real type once it is defined? Wouldn't that then allow users to write code that allows for all use cases under this scenario? - Damian (he/him) On Tue, Aug 10, 2021 at 1:55 PM Thomas Grainger <tagr...@gmail.com> wrote: > dataclasses need to check for ClassVar > _______________________________________________ > Python-Dev mailing list -- python-dev@python.org > To unsubscribe send an email to python-dev-le...@python.org > https://mail.python.org/mailman3/lists/python-dev.python.org/ > Message archived at > https://mail.python.org/archives/list/python-dev@python.org/message/WOTCUBAO62WRRCCQAO6ZJNASSMK36MDW/ > Code of Conduct: http://python.org/psf/codeofconduct/ >
