[1 of 2] Compiling Main ( Main.hs, Main.o )
Main.hs:12:7: warning: [GHC-63394] [-Wx-partial]
In the use of ‘tail’
(imported from Prelude, but defined in GHC.Internal.List):
"This is a partial function, it throws an error on empty lists. Replace it with 'drop' 1, or use pattern matching or 'GHC.Internal.Data.List.uncons' instead. Consider refactoring to use "Data.List.NonEmpty"."
