Currently, there is no way to reorder the tokens in a message string, and that is required for /some/ messages in /some/ languages. I have used my own text formatting routine rather than Phobos' because it allows the implementer to develop messages whose word order is correct for their target language.
Phobos has supported Posix positional syntax since 2.006. http://digitalmars.com/d/2.0/phobos/std_stdio.html Andrei
