[boost] [General] A standard idiom or technique?

A recent post in this list started me thinking...

Given this code snippet,

using namespace std;

void f( int, int );

vector<int> v1;
vector<int> v2;

// populate...

for ( unsigned i = 0; i <= v1.size( ); ++ i )
{
  f( v1[ i ], v2[ i ] );
}

How would you write this as a for_each() or in some other Boosty, functional
way?
(The aspect I'm trying to highlight is that two iterators over different
ranges must
advance in step)

One could imagine a tuple-based solution, in which one specifies how an
operation
applied to the tuple distributes to operations applied to each of the
tuple's elements.

Does any such thing exist in Boost? Is it ever necessary, or can the
functionality be
achieved by some C++/STL/Boost idiom that I've not thought of?

If there is no obvious technique, is there any interest in a Boost library
which address
this in a generic way?

Thanks.
