[Haskell-cafe] Cabal sandboxes over cabal-dev (Rogan Creswick)

[Gregory Guthrie]

   "I *strongly* suggest everyone start transitioning from cabal-dev to cabal sandboxes."

Is there any reason that this is not just the default install mode for Cabal?

Anything that prevents the current cabal-swamp of broken dependencies is a great help. I have tried to use Haskell in some classes, but it is hard when students (and I) cannot install packages, and the only answer is the Microsoft-like; "delete everything and start over; reinstall". It certainly reduces their confidence that Haskell is a feasible working environment.
