well, guess what, I ran some tests and here's my *BIG WIN*: the
non-destructive procedures seem to use about 5% less space than the
destructive ones.  OTOH, the destructive procedures are ~30% slower than
their non-destructive counter-parts.

I don't think that's a win in anyone's book  :(

After this little exercise, I suspect that the GC is a bit smarter than I
thought.  It must be.  With the test I ran, my hypothesis was that the
non-destructive guys would use at least 25% more space.  Not even close.
