They're working really hard on improving it though . Cabal 2.0 will have a nix-style build system, in which multiple verions of the same dependency can be installed globally (so no separate sandbox per project). This will solve most problems of where cabal breaks down. This gives us almost the same usefulness as Stack. However, you will have to make sure that there is actually a feasible build plan, by setting up your version bounds correctly. With stack, other people take care of this for you, and you never touch the version bounds, which is relaxing but also gives you less control.

A nice feature of stack that cabal AFAIK will not provide is that it takes care of installing GHC in multiple versions. I think that's very important for newcomers.

> relaxing but also gives you less control

More like "leads you to typically exercise less control". You can override versions of packages in a stack snapshot.

Cool I'll give it another go once they release it.
