[issue1173475] __slots__ for subclasses of variable length types
Ronald Oussoren added the comment: I do have a usecase for this: subclasses of int. Having slots would be nice for a reasonably efficient implementation of named constants (as recently discussed on python-ideas), and I'm already using a subclass of int of PyObjC to attach a single other value to a Python integer. In both cases the overhead of the __dict__ is pretty large. -- nosy: +ronaldoussoren versions: +Python 3.4 -Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1173475 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Raymond Hettinger rhettin...@users.sourceforge.net added the comment: ISTM the space saving of value of __slots__ isn't typically needed in the context of variable length built-in types. Guido has long regarded __slots__ as a confusing hack. That should warn us away for extending its functionality. Unless there are some compelling use cases, a simple and clean patch, and a clear one sentence explanation for users, I recommend this feature request be closed. Michael, do you still want this? -- nosy: +rhettinger ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1173475 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Michael Hudson m...@users.sourceforge.net added the comment: Well, I can think of some counters to that -- surely it's _more_ confusing if slots only works some of the time? -- but realistically I'm not going to work on this any further. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1173475 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
