The default constructor of vector_expression is private, because it is 
not allowed to directly instantiate a vector_expression. This means one 
cannot have functions like:

template < class V>
foo(const vector_expression<V> v);

but one has to use

template < class V>
foo(const vector_expression<V> & v); // note the reference!

maybe there are some mistakes of such type in the atlas bindings.

Can you check this?
