Looking at the error messages, and from what I've heard, it may be that it has problems with template friends (which is what the operator<< is). If that's the case, the workaround should be very easy - making it a free-function template. I did that, now, and it works. :) At least the vector_pair_test(). The array2D_test() uses a little fancy code, such as passing the type reference to array as a template parameter, and it seems MSVC 7.0 has some problems with this. Anyway, that was just to demonstrate usage with built-in types, as well, such as arrays. I'll look into it. There wasn't really any need for it to be a friend function, as it didn't access any private parts. It was just defined inside the class for convenience. I've also tested it on Intel C++ 7.0 in strict mode and g++ 3.2, so the code should be conformant, at least. Thanks for the report. I hadn't yet got around to do more portability testing, but intend to do that, including writing more tests for it. I've updated the version at Yahoo Groups with the above changes.
