I completely agree that the naming scheme is sound. I don't see, however, how other packages are going to use it. Could you show us a concrete example, please? What does a package like, say haskell-pandoc, depend on?
Well, I may be wrong (I'm not a pacman expert), but the haskell-hp-... packages contain "provides fields" for the corresponding versions of haskell-... packages. So it depends whether your version of pandoc package is expected to be used with the last haskell platform version, in which case it should require haskell-hp-... as a dependency, or whether it is supposed to be used with the latest versions of all of its dependencies, in which case it would require haskell-... package (with specified usable version range). If your last haskell platform has recent enough versions of libs then your haskel-pandoc package which depends only on haskell-... packages (if you wanted it to be bleeding edge) will compile and install just fine thanks to the provide fields in the haskel-hp... packages. My opinion is that everything bleeding edge (aur source code (self compile) versions) should depend only on haskell-... packages and not on haskel-hp-... packages. The only thing which can depend on haskell-hp-... packages are haskell platform packages themselves or something you want to provide in binary form and don't want to update it every time some dependency is updated. Since the latest versions are updated often and not everything compiles with them, it does not look useful to try to keep binary versions up to date for things which do not depend on haskell platform only. Of course it is possible to create a system which can answer a question like: "I want the latest possible version of pandoc, gtk2hs-gtk and gtk2hs-glade. Find the latest versions of these packages and the latest versions of all the packages these depend on recursively so that it all compiles fine." With a bit of luck one can answer this from the cabal files (provided their version dependency info is correct). Whether it would actually compile is another problem. And whether the result would work is something completely different.
