Comment (by slabbe):
Here is one benchmark.
BEFORE::
{{{
sage: w = Word([0,-1,2]*100, alphabet=[0,-1,2])
sage: type(w)
<class 'sage.combinat.words.word.FiniteWord_list'>
sage: %timeit w.is_square_free()
1000 loops, best of 3: 417 µs per loop
}}}
AFTER::
{{{
sage: w = Word([0,1,2]*100, alphabet=[0,1,2])
sage: type(w)
<class 'sage.combinat.words.word.FiniteWord_char'>
sage: %timeit w.is_square_free()
100000 loops, best of 3: 6.29 µs per loop
}}}
We should also add here some benchmark about equality test and also
`__getitem__`.
