[plt-scheme] Ambiguous grammar at bottom of 6.3 of PLT MzLIB

Hello all,

I found this at the bottom of 6.3 of the PLT MzLib: Libraries Manual:

 (define/public (header . formals) expr)
=expands=>
 (begin
  (public name)
  (define (header . formals) expr))

As you can see the expansion involves the creation of a name 
out of thin air; so this has to be a documentation bug.   I've 
tried to infer what it might be that the author actually meant 
to write, but I get syntax errors no matter how I've arranged 
things any time I add that decimal point in between what is 
being called the header and the formals.  In short, I just don't 
get it.  Has anyone used this syntax successfully?
