Probably like this:

#include <vector>
#include <algorithm>

#include <boost/function.hpp>
#include <boost/bind.hpp>
#include <boost/bind/apply.hpp>

int main()
{
     std::vector<boost::function0<void> > Methods;
     std::for_each(Methods.begin(), Methods.end(),  
boost::bind(boost::apply<void>(), _1));
}
