Should I use a seperate functor like this?

template<class T>
struct dereference : public std::unary_function<T*, T>
{
    T operator()(T *pt) { return *pt; }
};

A a;
boost::bind(&processA, boost::bind(dereference<A>(), _1))(&a);

If the answer is yes, is there a safer and stronger equivalence
of "dereference" in boost?

Thanks again.

======================================
Hello

On simple question:

For 

struct A {};
void processA(A& a) {}
A *pa = new A();

How to write a bind expression  that make 

(pa);

equivalent to

processA(*pa);

I've tried with this:

boost::bind(&processA, *_1)

but failed.

I've also tried with this:

processA(*boost::lambda::_1)

also failed.


Thanks for any information.

B/Rgds
Max
