The challenge is that I have to rework the parser to be aware of when it's
parsing arguments for a routine call, so that if it finds the PBR token,
it can remember that. Also, if it finds that token anywhere else, it
should cause an error.

Yeah, that was the dilemma I faced initially, and why I went with the
asterisk.
