[boost] [fusion] sequence member pointer

I am attempting to use a fusion sequence with a visitor pattern that expects 'member function' or 'member data' pointers.  

What I would like to do is something like:

&fusion::vector<int,double>::m1

But obviously this cannot work because of how fusion::vector<int,double> is implemented with a single vector_n<...> vec data member that is private.

So trying to "reflect" a vector in the same way that I "reflect" a struct does not work.

Any good ideas?   Is there any reason why this 'implementation detail' needs to be hidden?
