This is a summary of the replies I received to my enquiries
about "erasure by reference-counting". 

Apparently reference-counting is alive and kicking in Smalltalk-80's 
garbage collector.  It has also been used in Xerox's Interlisp. A
source of references is "The Implementation of Functional Programming 
Languages" by Simon L. Peyton Jones.

Thanks are due to the following:  Ray Fink, Robert Strandh, Mike Gigante, 
Peter Norvig, dmfloy, Keiji Kanazawa and kythera.

	Regards,
		Bill Birch
