Hi,
There is this mysterious line in scalar_expression<>'s definition:
private:
typedef typename LHS::value_type DummyType; //Visual C++
2005 does not allow to write LHS::value_type::value_type
This prevents us from using a scalar expression whose LHS is a
scalar_expression. This makes it impossible to write things such as
viennacl::element_sqrt(scalar_expression). (I need this for neatly
integrating norm_2 into the generator through the statement
element_sqrt(inner_prod(x,x)))
The comment is slightly mysterious. Is
typedef typename LHS::value_type value_type; not allowed?
I can't believe that VS would break template recursion so easily, but
perhaps I'm wrong.
