I wondered whether the method "key" will always be computable, but
discussing that with zagy I found out that doing __cmp__ requires one to
be able to normalize the string for a different comparison anyway, so
they key method would be the one doing that.

Eventually you might want to mention that the key() method would be
useful to implement as basis for __cmp__ anyway as it does the
normalization work, so __cmp__ should in any case be possible to derive
from key() ...

So, from me as well: +1
