Yesterday, I tried HP's new C++ compiler (3.0) and templates for the first
time. To my surprise, I noticed that operator -> can only return the following
three types:
   - a pointer to a class,
   - a class, or
   - a reference to a class.

This means I cannot do simple things like:

  template< class T >
  class OffsetPtr 
    {
    public:
      OffsetPtr();
      OffsetPtr( T* );
      ...
      T* operator ->();
      ...
    };

  OffsetPtr<char> ptrToString;


What is the rationale behind this restriction? I couldn't find anything in
C++PL 2nd ed. that mentions this restriction, although I didn't look too hard.
