[Boost-users] calling on the template gods

I have been attempting to hide the boost interface when using the boost
smart pointers. I basically want to get rid of boost declarations in my
API's. This basically involves typedef-ing template classes, and the best
solution I have been able to come up with is:

template <typename T>
struct pointer
{
typedef boost::scoped_ptr<T> obj;
typedef boost::scoped_array<T> arr;
typedef boost::shared_ptr<T> sobj;
typedef boost::shared_array<T> sarr;
};

so I can do things like pointer<int>::arr var(new int[10]). This works fine,
but if I try to get tricky it falls apart. Another example:

template <typename T>
class Stuff
{
private:
pointer<T>::arr some_stuff;
};

This does not work (I can't even start to tell you why), but I have hit the
point where I have to start second guessing my approach to this problem. Are
there other (possibly terrible) tricks to get around the typedef templates
problem? Any input will probably help.

-thanks
