Detailed Description

A view state into an fe::List <>

Do not access Context members except indirectly through List.

If you like iterators better, use fe::List::Iterator which wraps an fe::List::Context.

Context is similar to an iterator except that it does not contain a pointer to an List<>. All access to an List<> is done directly through List<> member functions with an Context argument. This means that Context is generic and does not need to be templated. The context is very lightweight and has no template instantiation. No special permissions are needed for context to list accesses. Your code always explicitly says which list it is accessing.
