Many years passed and people still struggle how to update all packages, like e.g. opam upgrade
can.
There is even a workaround like:
cabal list --simple-output --installed | awk '{print $1}' | uniq | xargs -I {} cabal install {} --reinstall
(taken from https://stackoverflow.com/questions/6905163/whats-the-best-workaround-for-not-having-cabal-upgrade/6905267#6905267 )
Would be nice to finally have it. (Yes, I know about Stack, but it's still far from being widely used).
