It appears another option is as follows: result_of::value_of<result_of::begin<VectorType>::type>::type or for an arbitrary index N enum { N=2 }; result_of::value_of<result_of::advance_c<result_of::begin<VectorType>::type,N>::type>::type Chris On 1/20/07, Sohail Somani <s.somani@fincad.com> wrote:
All the at functions would return you a reference, not a copy anyway. So they are doing the right thing. Stripping the reference is the right thing to do.

I tried this, but it seems to be the result of the at_c function which is a reference. I would like to get the type of the element. I suppose I could use a meta-function to strip off the &, but it seems like the mpl version of at_c should do what I want. Chris

Hi, I am trying to get the type of the first element in a fusion vector using mpl::at_c. This seems simple enough.

I'm a noob to fusion but do you want fusion::result_of::at_c instead? _______________________________________________ Boost-users mailing list Boost-users@lists.boost.org http://lists.boost.org/mailman/listinfo.cgi/boost-users
