 If I try to upgrade all packages it fails because syb wants a newer base:

 $ cabal upgrade
 Resolving dependencies...
 cabal: cannot configure syb-0.1.0.0. It requires base >=4.0
 There is no available version of base that satisfies >=4.0

 I don't want to upgrade GHC (in fact I can't right now) but I presume that
 there are other packages that could upgrade. Rather than run `cabal
 install' on them one by one, what about upgrading everything that is
 upgradeable, i.e. happy with the current base? There is a (misleading)
 analogy to the way apt treats releases -- it won't tell me "Can't upgrade
 because you're using the wrong release", but releases are self-contained
 and upgrades take place within that context...but obviously different
 because there you have different package lists for different releases...
