On a similar note, it would appear that the following is not possible
with v1.32:
vector<double> a, b, c;
c = project(a+b, range(i,j));
This fails because the expression created to represent a+b doesn't have
a vector_temporary_type, which the proxy (vector_slice in this case,
which also seems strange) seems to require.
This goes against the type requirements in the documentation for vector
slice, which states that vector_slice's template parameter must be a
model of Vector Expression.
