+
+In the Warlock, SpellBook and TargetGenerator classes, the switch statement is
+FORBIDDEN and its use would result in a -42.
+
+Create the following two spells, on the same model as Fwoosh:
+
+* Fireball (Name: "Fireball", Effects: "burnt to a crisp")
+* Polymorph (Name: "Polymorph", Effects: "turned into a critter")
+
+In addition to this, just so he won't have only dummy to attack, let's make a
+new target for him, which will be the BrickWall (Type: "Inconspicuous Red-brick Wall").
+
+Now, make a SpellBook class, in canonical form, that can't be copied or instantiated
+by copy. It will have the following functions:
+
+* void learnSpell(ASpell*), that COPIES a spell in the book
+* void forgetSpell(string const &), that deletes a spell from the book, except
+  if it isn't there
+* ASpell* createSpell(string const &), that receives a string corresponding to
+  the name of a spell, creates it, and returns it.
+
+Modify the Warlock, now, make it have a spell book that will be created with
+him and destroyed with him. Also make his learnSpell and forgetSpell functions
+call those of the spell book.
+
+The launchSpell function will have to use the SpellBook to create the spell
+it's attempting to launch.
+
+Make a TargetGenerator class, in canonical form, and as before,
+non-copyable.
+
+It will have the following functions:
+
+* void learnTargetType(ATarget*), teaches a target to the generator
+
+* void forgetTargetType(string const &), that makes the generator forget a
+  target type if it's known
+
+* ATarget* createTarget(string const &), that creates a target of the
+  specified type
+
+Phew, that's done. Now here's a test main. It's not very thorough, so make sure 
+to use your own aswell.
+
+int main()
+{
+  Warlock richard("Richard", "foo");
+  richard.setTitle("Hello, I'm Richard the Warlock!");
