Is this the only place where a non-class object with __bases__ is accepted? Or do we have more such? I recall that long ago you could use certain non-class objects as base classes.
I think all that hackery may predate (and may even have been an inspiration for features of) new-style classes. —Guido On Sat, Oct 3, 2020 at 03:12 Serhiy Storchaka <storch...@gmail.com> wrote: > 03.10.20 12:45, Steven D'Aprano пише: > > > On Sat, Oct 03, 2020 at 11:41:16AM +0300, Serhiy Storchaka wrote: > > >> issubclass() accept types (extension types and new-style classes), > > >> classic classes and arbitrary objects with the __bases__ attribute as > > >> its arguments. > > > > > > I didn't think classic classes were still possible in Python 3.
