what is the recommended way (fewest keystrokes) for:
* cabal install foo (download from hackage)
* build failure => edit sources => repeat install on modified sources
Is it really "cabal fetch foo"
then "tar xvfz ~/.cabal/some/very/long/pathname.tgz" ?
during the original "cabal install",
sources seem to be in /tmp/TMPfoo-*/*
but they are removed on failure.
or - is this a workflow that should not happen
(e.g. it might lead to confusing error messages later
because "ghc-pkg list" shows the original version number
if I forget to bump it while patching the sources)
