Sooooâ¦. I made a slice, but how does one save to the new inbox? You need credentials + some sort of access privileges all of a sudden? :S Cheers, Henry

Re: [Pharo-project] NewListModel and AlainTreeModel

by Benjamin

Of course not, but I just can't name the two tree implementation TreeModel. As I said in my mail, I will push AlainTreeModel as default, and it will be named TreeModel. Same for the list. (that's also why they do not have a class comment) Ben On May 3, 2013, at 8:10 AM, "Torsten Bergmann" <astares(a)gmx.de> wrote: > maybe it is just me ... but will we continue to name classes like this? > > => NewListModel (will it still be new in year 2052) > => AlainTreeModel (followed by StefsNewTranscript, BenObject, IgorNBWinConstants, ...) > > What was the timeline for namespaces? > > Bye > T. > > >

[Pharo-project] NewListModel and AlainTreeModel

by Torsten Bergmann

maybe it is just me ... but will we continue to name classes like this? => NewListModel (will it still be new in year 2052) => AlainTreeModel (followed by StefsNewTranscript, BenObject, IgorNBWinConstants, ...) What was the timeline for namespaces? Bye T.
