But there's a solution: we could remove the "standard" modules from base, and have them only provided by haskell-std (since base will just be a re-exporting layer on top of base-internals, this will be easy to do). Most packages will then have dependencies that look like
build-depends: base-4.*, haskell-std-2010
We'll probably end up with situations where one dependency of a package needs haskell-std-2010, and another needs haskell-std-2011. I don't know which impls support that at the moment.
That's the case with base-3/base-4 at the moment. Is it a problem?
Could I use two packages of arrow code which depend on base 3.0.2 and
base 3.0.3, respectively, in the same project?
