Perhaps you could clarify something: I tried suggesting a while ago that Sage start using language_level=3 at least when actually building Sage on Python 3. I know this isn't necessary but it just seemed to make logical sense. But Jeroen was convinced it wasn't necessary because, according to him, language_level=3 doesn't really do anything. So what exactly does language_level=3 (or 2) do, such that it would impact porting Python 3 code to Cython? _______________________________________________ cython-devel mailing list cython-devel@python.org https://mail.python.org/mailman/listinfo/cython-devel
