[1 of 2] Compiling Main ( Main.hs, Main.o )
Main.hs:27:15: warning: [GHC-63394] [-Wx-partial]
In the use of ‘head’
(imported from Prelude, but defined in GHC.List):
"This is a partial function, it throws an error on empty lists. Use pattern matching or Data.List.uncons instead. Consider refactoring to use Data.List.NonEmpty."
