These images just take the corresponding regular image (based on pharo 1.1) and apply the change set produced by Lukas. I attached the changeset here for convenience.

Re: [Pharo-project] Why is readStream on SequenceableCollection and not on Collection?

by Schwab,Wilhelm K

This cropped up in Dolphin some years back. IIRC, OA's answer was that streams historically worked on only Array and maybe something else. Having said that, they relaxed a constraint because it was harmless and a good idea. I'm not sure about streaming over a set; lack of order means that it might be tricky to maintain a reasonable position?? ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of StÃ©phane Ducasse [stephane.ducasse(a)inria.fr] Sent: Tuesday, August 24, 2010 7:18 AM To: Pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] Why is readStream on SequenceableCollection and not on Collection? did you try with nile? because I forgot (of course doing too many things) but the difference between squeak and VW was that we could not have a stream on something else than string and array.
