[Haskell-cafe] I do not want to be a bitch, but ghc-6.8.3 and haskell binary policy are really horrible.

is this correct? i was under impression that upgrading packages never
require to recompile GHC itself. it just happen that we have only one
version of base or array shipped with each GHC and at least with array
this can be changed easily (and for base too - just noone plans to do
it)
