Comment:
Hi,
I also thought about using the python string methods to fix this, but the
`Word` class allows arbitrary alphabet so we cannot use the method
directly.
The problem arises for example with `u = Word([-1,-2,-3])`, where `str(u)`
returns the string `'-1,-2,-3'`:
{{{
sage: u = Word([-1,-2,-3])
sage: v = Word([-2])
sage: u.find(v)
1
sage: str(u).find(str(v))
3
}}}
