Well,

if you switch to functors, instead of functions I can offer you the following example ;) But I am
unsure if it really suits your needs.

#include <iostream>

template<class T>
struct function_template
{
        void operator()(T value)const
        {
                std::cout << value << std::endl;
        }
};

template<class T>
struct other_function_template
{
        void operator()(T value)const
        {
                std::cout << value*value << std::endl;
        }
};

struct function_template_wrapper
{
        template<class T, template<class> class Function>
        static inline void call(T value, Function<T> f = Function<T>())
        {
                f(value);
        }
};

int main(int argc, char* argv[])
{

        function_template_wrapper::call<int, function_template>(10);

        other_function_template<int>	of;
        function_template_wrapper::call(10, of);
}
