    What is this +INTERNAL-HERALD-VERSION ...
    Furthermore, just sticking this function randomly into
    DEFMAX causes DEFMAX to be multiply-loaded in some environments,
    e.g. the macsyma compiler.
This might be a small subr in the system -- for now, the easiest way to
retro-fit it into old lisp environments was to have it come in as an
expr on some other file.  Your observation about "multiply-loaded" 
means only "loaded a second time", since lisps dumped out with an
old defmax in them will have to be "refreshed".
   Its entirely reasonable also just to have the HERALD macro produce
a gazillion lines of expr code.
