I understand this may not be ideal but I really see this as very narrow
use case - if you really want to compare strings in lexicographical
order, you just should use strcmp. So I think this fixes common cases
where people have high WTF factor, and if we later have better idea on
how to fix all the cases we could amend it further. But I'm not sure
adding more magic to the mix (i.e. doing special comparisons, etc.) is
going to be better - it will only make it harder for people to understand.
