Actually Arch has been accommodating in other cases when there was a stable library and a new/developing. It certainly keeps around two versions of python, autoconf, GTK, qt, gambas... The solution I'm proposing would be a little different than those cases, but on the same principle.

There need not be. Your works-for-me is great but it is meaningless to those of us who use ghc as a tool for larger projects. " This is not specific to GHC. Arch Linux, being a bleeding-edge Linux distribution, tends to prefer newer versions of software over more stable versions of software. I doubt that facet of Arch Linux will ever change, so perhaps you should reevaluate your choice of Linux distribution or avoid pacman/package updates for software whose stability and predictability is critical to you.
