Use bind to call a free function on a vector of shared_ptrs?

struct A { };
void f(const A&);
std::vector<boost::shared_ptr<A> > v;

for_each(v.begin(), v.end(), boost::bind(f, ???? ) );

what goes where ???? is?

Two tactics spring to mind.

One is to use boost::make_indirect_iterator on v.begin() and v.end() and just pass in f instead of the boost::bind(...).

The other is to use RangeEx (shameless plug) thus:

using namespace boost::adaptors;
boost::for_each(v | indirected, f);

Thanks, Rob.
