With the latest from svn, the types are:

boost::numeric::bindings::result_of::size< double[10] >::type
== mpl::int_<10> ...as expected

But boost::numeric::bindings::result_of::size< ublas::bounded_vector<double,3>
>::type == ptrdiff_t ...which is not what we want.

...and in likely related code
The following assertion work:
static_assert(boost::numeric::bindings::has_static_size<double[10]>::value, 
"Failure of traits");

And the following fails.
static_assert(boost::numeric::bindings::has_static_size<
ublas::bounded_vector<double,3>>::value, "Failure of traits");
