Compile error on ghc-8.2.2

Using stack to install I get the following error:

Sorry I'm too new to haskell to be much help in fixing :(

I've just uploaded a new version. I believe that should fix the problem. (I'm afraid I don't know stack well enough to give specific instructions for how to access this new upload. You'll have to get stack to refresh its package list from hackage.haskell.org.)

I had actually fixed this problem months ago, but never fixed the last niggling validation error and uploaded. It's all set now, in any case.

Thanks for posting!
