In Exercism v1, we had the rule to organise all exercises in config.json by difficulty. In Exercism v2, this does not make much sense anymore since it doesn't reflect the...

I'm opening this issue to see if there are any existing efforts to port [variable-length-quantity](https://github.com/exercism/problem-specifications/blob/main/exercises/variable-length-quantity/description.md) to Haskell. If not I'm happy to take this on myself - so far I...

This doesn't point to a `canonical-data.json` file, because none exists: [problem-specifications](https://github.com/exercism/problem-specifications/tree/master/exercises/tree-building) I stole all of the tests from the `go` track. I think it would be good to have tests...

When `stack test` fails, a part of its output is: ``` Failures: test/Tests.hs:20:23: 1) isLeapYear 1996 - year divisible by 4, not divisible by 100: leap year expected: True but...

bug

I expect that the main party motivated to actually fix this issue will be the maintainers of this repo, so I intend this issue as mostly a reminder that the...

In #435 we update to lts-7.9. Is there a rule for how often we want to do this? For example, lts-7.15 is out now. Or is it just "we update...
