Hi Vincent, Please try http://www.smalltalkhub.com/#!/~SvenVanCaekenberghe/Neo but the config will go back to the other repository. I'll have a look at the server ASAP.

I'm sorry to endorse the role of naughty conservatism (probably a problem of age), but introducing a touch of damping to slow the system down don't hurt. Anyway, any doer is responsible for his/her changes and can be prepared to rants, Funnily I'm also being questionned in the same time for having changed ($a to: $z) to return a String rather than an OrderedCollection in Squeak, We must accept that, every change is questionnable. Personnaly I try to rationalize rants, and rationalize changes, or at least put them in a longer term perspective, but at the end, some changes must always be done arbitrarily. 2013/7/18 StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> > Hi nicolas > > I agree :) > So we should find the right balance. > Stef > > > For FileSystem, there is a clear win, so I'd say the change is really > worth. > 1) you add more capabilities > 2) more logical/convenient API > 3) more efficient implementation > 4) more scalable implementation > The optional compatibility layer you offered is the exact solution to the > upgrade problem (you give a bit of time to maintainers) > I buy it. > > For and:and:and: etc...
