+
+In the Warlock class, the switch statement is FORBIDDEN and its use would
+result in a -42.
+
+Create an abstract class called ASpell, in Coplien's form, that has the
+following protected attributes:
+
+* name (string)
+* effects (string)
+
+Both will have getters (getName and getEffects) that return strings.
+
+Also add a clone pure method that returns a pointer to ASpell.
+
+All these functions can be called on a constant object.
+
+ASpell has a constructor that takes its name and its effects, in that order.
+
+Now you will create an ATarget abstract class, in Coplien's form. It has a type
+attribute, which is a string, and its associated getter, getType, that return a
+reference to constant string.
+
+In much the same way as ASpell, it has a clone() pure method.
+
+All these functions can be called on a constant object.
+
+It has a constructor that takes its type.
+
+Now, add to your ATarget a getHitBySpell function that takes a reference to
+constant ASpell.
+
+It will display :
+
+<TYPE> has been <EFFECTS>!
+
+<TYPE> is the ATarget's type, and <EFFECTS> is the return of the ASpell's
+getEffects function.
+
+Finally, add to your ASpell class a launch function that takes a reference to
+constant ATarget.
+
+This one will simply call the getHitBySpell of the passed object, passing the
+current instance as parameter.
+
+When all this is done, create an implementation of ASpell called Fwoosh. Its
+default constructor will set the name to "Fwoosh" and the effects to
+"fwooshed". You will, of course, implement the clone() method. In the case of
+Fwoosh, it will return a pointer to a new Fwoosh object.
+
+In the same way, create a concrete ATarget called Dummy, the type of which
+is "Target Practice Dummy". You must also implement its clone() method.
+
+Add to the Warlock the following member functions:
+
+* learnSpell, takes a pointer to ASpell, that makes the Warlock learn a spell
+* forgetSpell, takes a string corresponding a to a spell's name, and makes the
+  Warlock forget it. If it's not a known spell, does nothing.
+* launchSpell, takes a string (a spell name) and a reference to ATarget, that
+  launches the spell on the selected target. If it's not a known spell, does
+  nothing.
+
+You will need a new attribute to store the spells your Warlock knows. Several
+types fit the bill, it's up to you to choose the best one.
+
+Below is a possible test main and its expected output:
+
+int main()
+{
+  Warlock richard("Richard", "the Titled");
+
+  Dummy bob;
+  Fwoosh* fwoosh = new Fwoosh();
+
+  richard.learnSpell(fwoosh);
+
+  richard.introduce();
+  richard.launchSpell("Fwoosh", bob);
+
+  richard.forgetSpell("Fwoosh");
+  richard.launchSpell("Fwoosh", bob);
+}
+
+~$ ./a.out | cat -e
+Richard: This looks like another boring day.$
+Richard: I am Richard, the Titled!$
+Target Practice Dummy has been fwooshed!$
+Richard: My job here is done!$
