A fusion transform_view of a random access sequence should itself be a random access sequence, and its category is random access, but it doesn't seem to implement the complete interface. For instance:
struct plus1 { template<typename T> struct result { typedef T type; }; template<typename T> T operator ()(T const &t) const { return t + 1; } };
template<typename V> void bar(V const &v) { boost::fusion::at_c<1>(v); // OK boost::fusion::transform_view<V const, plus1> view(v, plus1()); boost::fusion::at_c<1>(view); // ERROR }
int main() { bar(boost::fusion::make_vector(1,2,3)); return 0; }
I can't randomly access elements of a transformed fusion::vector. Bug?
The at_impl had been completed omitted. I've fixed this in the cvs, and added covering tests. Thanks for spotting this.
