Microlens doesn't build with GHC-8.8.1 #124

Closed recursion-ninja closed 5 years ago

I tried to build with commit 537b9a55f158b375f76f2abda455319772277694

But it fails, due to MonadFail.

GHC 8.8 is not released yet. The 8.8-compatible branch is at #111.

Actually, whatever, I'll release a patch version now.
