I really hated the namespace separator and I ranted against it pretty heavily before PHP 5.3 was released. But I've been using PHP 5.3 pretty heavily for a new project and now I don't mind the backslash at all.
I also understand the technical need for a new character (which doesn't exist for static languages or some other dynamic languages) and once you need a new character then the backslash is a reasonable choice.
