FWIW, remove_pointer could handily be used to implement is_pointer:
template <class T> struct is_pointer
{static const bool value = !is_same<T, typename
remove_pointer<T>::type>::value;};
(assuming of course that remove_pointer removed pointers and top-level
cv-qualified pointers, else returned the original type)
template <class T> struct remove_pointer {typedef T
type;};
template <class T> struct remove_pointer<T*> {typedef T
type;};
template <class T> struct remove_pointer<T*const> {typedef T
type;};
template <class T> struct remove_pointer<T*volatile> {typedef T
type;};
template <class T> struct remove_pointer<T*const volatile> {typedef T
type;};
