Comment (by vbraun):

 You shouldn't return lists from @cached_method functions. If somebody
 mutates the output list then future calls return the wrong result! Always
 return tuples instead of lists unless you want the output to be mutable.

 Also, `ConjugacyClass` is a parent without elements; Use `SageObject` as
 base for classes that do not use the parent/element pattern.
