Oh yeah, that's right.

Got me.  You're the expert, by default, on this one.  I see the conundrum now, 
however...

John, would it be possible to issue that warning just the first time that 
graw() is called?  I've done stuff like that before:

 static bool graw_first_call = true;
 if (graw_first_call)
   graw_first_call = false;
   issue_warning();
 else
   execute_graw_in_legacy_fashion();
 end
