+-- A few notes related to the exercises of this lecture:
+-- 1. All defined functions and types have explanatory comments, since they are
+--    required by the assignment.
+-- 2. All functions are way messier than they should be, since the assignment is
+--    all about code golf (i.e. trying to write the shortest function or program
+--    that can achieve a given task).
+-- 3. The solutions I wrote in this file use features of the Haskell language
+--    that have not been explained in lectures, yet, and I did so because no
+--    rule says I can't. The features are: lambdas, where clauses, and type
+--    definitions. (Did I forget some?) Also, without those features, the code
+--    would have been way longer.
