I hear what you are saying... and perhaps the problem is that in all of my
code bounded_vector, etc. are used as both a statically sized and a statically
allocated matrix since I didn't have any other options.

Regardless, I needed to use this kind of metafunction to do what I have
been suggesting.  The ones I made were:
static_vector_size<bounded_vector<double, 3>::type == mpl::int_<3>
is_bounded_vector<bounded_vector<double, 3> == mpl::true_

Since ublas doesn't make the distinction between static size vs. allocation,
perhaps the better names are:
has_static_allocation<> and static_allocation_size<>
