Comment (by vdelecroix):
Replying to [comment:20 slabbe]:
> Why `Words_n` inherits for `Parent` instead of `AbstractLanguage`?
`AbstractLanguage` is designed to disappear. For the moment it just holds
the `_alphabet` attributes and some deprecated methods. I am not sure that
all language should keep this `_alphabet` attribute. That can be changed.
Do we want that languages implement a method `alphabet` or simply provides
an alphabet to the constructor of a base class?
`Words_n` does not care about an attribute `_alphabet` since it is
initialized with a `FiniteWords` as first argument. It is essentially an
empty shell.
