One use of "new" is to allocate an array of simple objects.  Another
is to allocate space for an object with a constructor.  In the latter
case, what would be the semantics of a realloc operator?  It makes
no sense, given strong typing, to extend the size of a single class
object.  There are possible uses for a realloc operator, but the
semantics get a little muddy.
