 I guess this may be controversial, but I have always liked the fact that
 cabal and GHC rely as little as possible on environment variables.

 It has made it much easier many times for me to debug ghc issues (funnily,
 especially the linker investigation) because I can see all relevant inputs
 to a ghc invocation simply in `ps` or `strace`, and re-run them to isolate
 problems without accidentally not replicating the environment correctly.
