Hello,
I've been trying 6.4 on one of my libraries and it seems it doesn't like my package names. I give my packages the same name as their place in the module hierarchy.
e.g. name: Data.COrdering
Is there any reason why this shouldn't be allowed? It seems so much more convenient this may, at least for packages the have just one root module.
Well (trying to answer my own question), I guess the reason for this change is probably Cabal related, so perhaps someone here can explain. Thinking about this, there doesn't seem to be any good reason for separate package names at all. It just means we have two name space problems instead of one (having to avoid package name and hierarchical module name clashes). Why not just use the root in the hierarchical module name space as the package name? (or use the package name as the root in the hierarchical module name space). So the OpenGL package should be called "Graphics.Rendering.OpenGL", or drop the "Graphics.Rendering" prefix, keep OpenGL as the package name and name its modules accordingly (OpenGL.GL, OpenGL.GLU etc..). (I think it would be rather nice to be able to tell what package a module came from by looking at it's name.) But I definitely think the most obviously appropriate (I.E. consistent with hierarchical module scheme) package names like "Data.COrdering" should at least be legal. Regards -- Adrian Hey
