Thank you for considering this.

1. The patch I sent is intended as proof of concept. The purpose is to
demonstrate that we can introduce the desired resize into storage, vector,
and matrix without breaking existing code. So far, the patch introduces
changes to storage::unbounded_array, and vector. To complete the job, we
need to look at other storage classes and other containters.

2. The testing I've done is only that my current batch of code, which uses
ublas quite a bit, still compiles and seems to produce the same results. I
don't have any real regression test, or specific test of the the new

3. OTOH, I think this change is simple enough that we can mostly convince
ourselves that it is correct by inspection, providing it doesn't break

4. My comment about enable_if is probably wrong - but if we accept that
vector<bool> is not important - then maybe we can just ignore it.
