As Elizabeth mentioned, your example (freeing the memory after doing
just a few operations) could have been done with PAD or ALLOT instead of
ALLOCATE.  In a more typical case, when you create a string, it's for
some other part of the program to use, so the place that creates it
doesn't know when it will be freed.

That's the old-fashioned C++ approach, and part of the reason people
complain about C++ programs being slow and memory hogs ;-).  You also
need complexity in each of your containers to free the memory of objects
inside the container when the container is freed, etc.  What happened to
factoring?  GC puts all the freeing in one place.

Even in the cases where you got by without it, maybe it could have saved
you some effort if you had used it.
