You might be able to get scoped_array to work for this case, but it's not
likely. The scoped_xxx classes work well enough for use in local variables,
but they're unlikely to be good enough to work well for class members.

The normal solution for what you describe would to to use a vector instead
of a scoped_array. Is there a good reason you can't do that instead?
