I definitely don't think using lists would be the right thing.

As Guido says, having the canonical form for an absolute location be
u'foo/bar' would be fine with me. It's even more canonical than a tuple
of names because a name isn't allowed to have a '/' in it (and all other
Unicode characters, or the empty string, are allowed).

OTOH I'm willing to be convinced that a class is the best way to do it,
but I'm not swayed by the arguments I saw.
