But it's not just about messages; we'd also need doLayoutInWorkspace and emptyLayoutInWorkspace. In particular xinerama support would not work without those. Since PerWorkspace is the only layout that could possibly use this information, adding three new methods to the LayoutClass just for this is almost certainly not the way to go.
Ok, so, if I get it right, you are proposing to go back to existential and everything just because you think it is wrong to extend a class, which, I was told, is just something you can extend without breaking what is built upon it. All this because you suppose PerWorspace is the only one that *may* be using a non pure combinator. Well, just today Joachim was asking for something like a combinator, implemented as another hook. Brent, even though I really like your code, I must confess I *totally* disagree with your design principles. Cheers, Andrea
