Experiencing problems with the identity of Characters I realized that

    $a clone = $a -> false.

In other words, it is allowed to #clone or #shallowCopy a Character but #=,
being implemented in Character, answers false when the copies are compared
with the original objects.

I overridden #clone and #shallowCopy in Character answering self. Is this
OK?

Saludos,
Leandro
