Any ways to test a GHC build against large set of packages (including test suites)?

[Artem Pelenitsyn]

Hello Ömer,

Just a week ago I asked very similar question: how to install the test
suite dependencies after breaking changes in GHC:

https://mail.haskell.org/pipermail/ghc-devs/2018-August/016075.html

But no one replied :(

The task seems to be not solvable even if an affected package (stm in your
case and primitive in mine) has already adopted in its master the breaking
change but has no corresponding release on Hackage (which will always be
the case, because how would you release depending on base which hasn't been
released yet).

Some package managers in other languages (Julia's Pkg, go install) allow
you to depend directly on master branch of a package if you wish to. I
wonder if there is a road here for cabal to take in order to support this
kind of unsafe installs.

Best wishes,
Artem
