(a) Occasionally one encounters the suggestion that a garbage-collected language should provide a delete operation as an optimization: by explicitly delete-ing objects that will never be used again, the programmer might save the garbage collector the trouble of finding and reclaiming those objects automatically, thereby improving performance. What do you think of this suggestion? Explain.

(b) Alternatively, one might allow the programmer to “tenure” an object, so that it will never be a candidate for reclamation. Is this a good idea?
