Should I be able to forward declare something from a namespace different
from the current one? For example the following code compiles:
//testdriver.hpp
#ifndef TESTDRIVER_HPP
#define TESTDRIVER_HPP
#include <ostream>
namespace ns_testdriver{
using std::ostream;

How do you forward declare a class that is *not* paramaterized, but is
based on a template class?
Here's what I thought should work, but apparently doesn't:
class Foo;
void f1(Foo* p)

Hi
I have a question on usage of forward declarations of templates. While
searching through this group , people suggested using forward
declarations and typedefs for templates as
// in myfile.h
template<typename T,typename R>
class some_class;

Hello, I was wondering if it is possible to forward declare a type
definition. If so, what is the way to do it? I found a couple of
messages where they say it's not possible but there must be a way to
do it.
Thank you.

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention.

Now, this would greatly impact the work of software developers. The idea...
