I've had a dump() subroutine for years but never happened to 
dump($GLOBALS) before, go figure.  So, var_dump($GLOBALS['GLOBALS']) 
works fine, and shows ["GLOBALS"]=>  *RECURSION* so clearly it can 
identify $GLOBALS['GLOBALS'] either as a special-case or through some 
other mechanism.  I can certainly deal with it as a special-case until I 
have time to figure it out, but is there some cleaner way to identify a 
variable that is itself recursive?
