What is the state-of-the-practice in type-level programming?
I know Günther started this thread about monads, but I seem to
remember him having a long running problem with typeful database
programming, and I wonder if some of his problems are really in the
later area. Compared to monads,

A while ago I gave up on trying to get GHC 6.12.1 working, for I lost the
battle building cabal on my windows machine
It would help A LOT when cabal.exe could be downloaded somewhere...
Thanks

Hello,
why I can't define a recursive vector using Data.Vector, like in
the example:
import qualified Data.Vector as V
let fib = 0 `V.cons` (1 `V.cons` V.zipWith (+) fib (V.tail v))
There's a typo:
fib = 0 `V.cons` (1 `V.cons` V.zipWith (+) fib (V.tail fib))
Which let's it
