I have discovered an interesting issue during the implementation of my
garbage collection project.

There does not appear to be a portable way to copy an object from one
memory location to another.  The operator '=' might be overloaded, so
I cannot depend on it for copying.

If I can copy an object, then I can compact the memory when doing garbage
collection.  Right now, heap fragmentation is a possibility.

On the other hand, the C language has always the problem of heap fragmentation,
and yet it's the most popular language!
