	I know about the deficiencies of refcounting.  However, it was
	my understanding that it works quite well for Perl in practice.

	Given that Go has no pointer arithmetic, I'd say that these are
	"safe references."

	I may be using a wrong term, but the GC's I've worked with
	typically allowed for a procedure to be run when an object
	is about to be removed.

	How would, say, Perl's IO handles be possible without the
	availability of a mechanism to properly give the resources back
	to the underlying system when such a handle is to be removed?
