Please update the bounds on base to base >= 4.8 && < 5: https://github.com/bjpop/language-python/blob/dfa446c76f8073dac44159169a619eb61922e11c/language-python/language-python.cabal#L30 I did this update as revision to version 0.5.8.

Sorry for the delay on this.

It is still an issue, I only have GHC 8.10.7 on my machine.

Everything builds and runs correctly on GHC 8.10.7 for me.

If you still need a change please submit a pull request.
