Nope, wrong again. If ar's type X is dependent and "register_type" is a nested template in X, then you need "ar.template register_type<...>". Otherwise, you need "ar.register_type<...>"
A-la typename usage:
typename dependant_name::nested_type
dependant_name.template nested_template
Exactemundo.
From the above code it could be either. Its really annoying to me to have to keep the context and provinence of a variable like "ar" in my head while I'm writting.
Guess what; you don't. If you had to know whether ar was a template or not, just think how impossible it would be to write generic code?
Well, you *do* have to know if ar is a class template, but not if it's a template class, which is what I think you were trying to say.
No, I was using colloquialism. After all, "ar" is a variable, not a type or a template. The only interpretation that could possibly make sense is that I meant "ar's type is a class template specialization." -- Dave Abrahams Boost Consulting www.boost-consulting.com
