The R6RS has a grammar description of the datum syntax for numbers which  
includes the @ and normal complex forms. I don't know if any of this has  
been used in the current report, but previous standards have provided  
information on it. The TSPL also contains a more general description, but  
my understanding was that this syntax was purposefully fairly vague.
