eliminate dependency on MonadFail #212

Closed farrellm closed 4 years ago

farrellm commented 5 years ago

There was a potentially incomplete pattern match inside a do block that triggers a MonadFail dependency. This change eliminates that pattern match, so MonadFail is no longer needed. This allows the build to succeed on recent versions of GHC.

The change is good. Any chance of merging this?

Anyways, here is another case of a MonadFail dependency that cannot be avoided and leads to a compile error for newer versions of GHC: https://github.com/svenkeidel/husk-scheme/commit/e0276d0a9ef549572f3efaed9445e7396e3d5034
