Module Test.QuickCheck.Instances collides with a module of the same name from checkers

[sol]

From a users perspective this is a pain, esp. when using a global package database and GHCi. checkers was first, quickcheck-instances is more widely used. Not sure how to resolve this.

I'm okay deferring to checkers after a deprecation cycle, although I'm not sure what a good window is to leave my version of Test.QuickCheck.Instances around.

I also wouldn't mind moving to a less "official sounding" module - something like Test.QuickCheck.Util.Instances or Test.QuickCheck.Contrib.Instances.

Pinging @nick8325 to see if they have any preferences.

Looking at checkers again, it also uses module names like Test.QuickCheck.Utils. I would tend to solve this in checkers and move everything from Test.QuickCheck.* to Test.Checkers.* (with a deprecation cycle of course). @conal what do you think?

Is there are movement on this issue? I just ran into it, but it seems quite old - if there's a systemic way to solve this I'd love to know about it!

Just discovered PackageImports, which totally solved this for me.

import "quickcheck-instances" Test.QuickCheck.Instances()
import "checkers" Test.QuickCheck.Instances()

Sorry for the noise!
