ISO C++ requires type names (as opposed to other kinds of names) dependent
upon a template parameter to be qualified with the keyword "typename". Some
compilers make do without the 'typename', although the code is not
compliant without it.

"//" is sufficient to mark a comment in C++.
typedef typename std::map<K,D,C>::iterator iterator;
typedef typename std::map<K,D,C>::const_iterator const_iterator;
The rule is that std::map<K,D,C>::iterator is assumed to be the name of
an object unless you say that it's the name of a type.
