The fact that we allow setting to the dictionary when we shouldn't be much to worry about - it is just odd. In either case we still have a .NET type defined something like:
class NewType : YourBaseTypeHere { public PythonDictionary __dict__; public object[] __slots__; ... } And it's just in one case we don't allow anything in __dict__ and in another case we do (the types do look a little different between v2 and v2.6 but not enough to matter). I could see us backporting just the fix for calculating whether or not slots is allowed but not the restructuring of the new-type maker code. But I think the justification for that isn't the oddness here but cases where in 2.0.1 slots are valid but we don't allow them (which I'm fairly sure exist as well). > -----Original Message----- > From: users-boun...@lists.ironpython.com [mailto:users- > boun...@lists.ironpython.com] On Behalf Of Michael Foord > Sent: Monday, March 09, 2009 6:36 AM > To: Discussion of IronPython > Subject: Re: [IronPython] __slots__ > > Curt Hagenlocher wrote: > > On Mon, Mar 9, 2009 at 5:28 AM, Michael Foord > <fuzzy...@voidspace.org.uk> wrote: > > > >> Curt Hagenlocher wrote: > >> > >>> I believe this is already fixed in the current (ie 2.6ish) source. > >>> > >> Any chance for 2.0.2? > >> > > > > That's Dino's call.
