Re: [Pharo-project] Pharo changing the game

by StÃ©phane Ducasse

here is also what I added to the blog entry "Improvements can be as simple as that. Now the first level is to communicate with people and let them know that they can improve if they want. So we will probably fix that in Pharo. If somebody provides a fix it can be fix in 2 min. The goal of pharo is to create an innovative Smalltalk that can be use to make business but also to reinvent Smalltalk. And this will not be done without breaking stuff. We do not want to live in a museum. http://www.pharo-project.org for more information and vision statement."

Re: [Pharo-project] Pharo changing the game

pfff.... I should say that kent should have not broken his rule. Don't blog when you are mad. It gives a bad impression and not only about smalltalk Now what is the solution. get stuck with a ANSI bad standard? get with vendors evolution that are not optimal? what if we do not like VW Namespace ? what if we would like to have first class instance variables? Vendors like parceplace did not really ask the community about the changes they did. Now Seaside is developed on pharo and run on nearly all the dialects so there is a path. It is not easy. Now if would be better to think that what is the future of smalltalk. - scripting - first class instance variables - new look at the MOP - better modules system - ... and we will not to that with ANSI kind of standardization process. Stef BTW this is fun because when I read the bio of Kent on his recent book I do not see Smalltalk mentioned so this is good to know that he is back to smalltalk :) > Interesting read (read [2] then [1]), maybe Pharo can change the game ... > > bye > T. > > [1] http://www.jarober.com/blog/blogView?showComments=true&printTitle=Balkaniza… > [2] http://www.threeriversinstitute.org/blog/?p=466 > -- > NEU: Mit GMX DSL Ã¼ber 1000,- Â¿ sparen! > http://portal.gmx.net/de/go/dsl02 > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project

I am against using #and:and: and #or:or:. It is slow, confusing and incompatible with any other Smalltalk out there.
