Template technicality - What does the standard say?

[Stephen Horne]

I've been using Visual C++ 2003 for some time, and recently started
working on making my code compile in GCC and MinGW. I hit on lots of
unexpected problems which boil down to the same template issue. A
noddy mixin layer example should illustrate the issue...

class Base
{
protected:
int m_Field;

public:
Base () : m_Field (0) {}
};

template<class Tclass Derived : public T
{
public:
void Inc ()
{
T::m_Field++; // GCC needs the "T::" here - VC++ doesn't
}
};

In the above, the idea is to use Derived<Base>, but GCC (3.4.5 and
4.1.2) gives error messages even if you never instantiate the
template.

There are of course examples of similar templates in Stroustrup, but
because they are incomplete examples, I can't find one that shows an
inherited member being referenced from within the template class.

In non-template classes, scope resolution is only needed to access
inherited members if there is an ambiguity. There is no ambiguity in
the above - the only place m_Field can come from is the inherited
class Base via the template parameter T. Following that general
principle, I don't see any reason why scope resolution should be
needed.

What does the standard say about this - should the scope resolution
operator be required? If it is required, what's the rationale? If
there's something in Stroustrup about this, can you point me to the
right section?

unnecessary stress reactions.

The point is that stress control techniques only work if I'm not
really all that stressed anyway.

Of course if you tried it without benefit I can't argue with that.
But I do think that "intact" is too strong a constraint -- it's not a
one-way street, and neither is acute "firefighti ng" the main point of
practice.

But let's not dwell off topic, I mainly just thought someone might
know that company.

Wouldn't they want people who can speak Swedish?

No. My friend's still digging, though.

In case anyone's interested, the name is Specialisterne.

Thanks for the pointer. A very interesting project.
