I think this is fundamentally the same issue as #76 , but it affects a different file, namely Set3b.hs.
I've submitted my solutions and they pass, but if I build on my machine I get this:
Mooc/Th.hs:27:14: warning: [GHC-63394] [-Wx-partial]

It's worth mentioning I compile with cabal exec runhaskell Set3bTest.hs.
