Is this what you want?

Hi,
I would like to bind to the boost::get<N> function for use by
transform iterator.
This is the pseudo code if get worked like a simple function.
std::vector<tuple<int,int,float> > v(2);
v[0] = tuple<int,int,float>(2,2,2.2f);
v[1] = tuple<int,int,float>(3,3,3.3f);
std::accumulate(
boost::make_transform_iterator(
v.begin(),
boost::lambda::bind(&boost::get<1>,_1)),
boost::make_transform_iterator(
v.end(),
boost::lambda::bind(&boost::get<1>,_1)),
0);
I find bind is difficult to use for functions that deduce template
arguments from function arguments.
I thought if I changed boost::get<1> -> boost::get<1,tuple<int,int,float> >
That didn't work either. Digging through tuple.hpp makes my head spin.
Is there an easy way to do this.
Thanks,
Chris
