Requiring base < 4.9 #4

Open tarquin-the-brave opened 4 years ago

tarquin-the-brave commented 4 years ago

Hello,

I've found this on hackage and have tried to use it.

I'm learning Haskell at the minute and have just handwritten my first Monad. I was looking to add some tests that it adheres to the Monad, Functor, & Applicative laws.

I rolled back the stack resolver to lts-5.18, to get ghc 7.10.3 with base 4.8.2.0. But my code uses MonadFail from Control.Monad.Fail, which came along in base 4.9.0.0. So I got a bit stuck.

What would you recommend?

I've just tried updating base in smallchack-laws and it's built OK.

I'll try upgrading the other dependencies and see if that works for my testing

I've tried forking this repo and its dependencies and changing the base version to be <5 and things seem to be working.
