[1 of 2] Compiling Main ( Main.hs, Main.o )
Main.hs:39:11: warning: [GHC-63394] [-Wx-partial]
In the use of ‘head’
(imported from Data.List, but defined in GHC.Internal.List):
"This is a partial function, it throws an error on empty lists. Use pattern matching, 'Data.List.uncons' or 'Data.Maybe.listToMaybe' instead. Consider refactoring to use "Data.List.NonEmpty"."
