From: Vladimir Grigoriev on 18 Jan 2010 09:16 Why is not compiled the following code in Visual C++ 2005 EE? template <template <typename T, typename A> typename Container, typename T, typename A> inline typename Container<T, A>::size_type size( Container<T, A> &c ) { return ( c.size() ); } Vladimir Grigoriev

Could you perhaps rephrase it? What do you expect, and why? What do you get? Post *complete* code and the compiler output and explain how it is different from what you expect.
