Sage implements an iterator on finite words n lexicographic order, and
such a thing is not possible. In particular:
{{{
sage: w=Words([0,1],infinite=False).__iter__()
sage: w.next()
word:
sage: w.next()
word: 0
sage:
sage: w.next()
word: 1
sage: w.next()
word: 00
}}}
I see two ways out: stop claiming that it is lexicographic, or remove the
function. What do you think?

P.S.: To whoever types "git blame" (like and did) and notices that I am
the author of the function: please look at the whole commit, I only moved
it to a different place `:-PPP`
