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?
No. (though I'm not sure the significance of "arrow code" here). Is
there a package that depends on base-3.0.2, and doesn't work with
base-3.0.3?
Cheers,
Simon
