/// Maintains an ordered list of name/value pairs representing

/// @note
/// This is a minimally-functional placeholder at the moment
/// to fill out the class hierarchy. The final class will be
/// something else, probably more pair-oriented. It's also
/// an area where shared values are desirable so refcounting is
/// already specced and a copy-on-write scheme imagined.
/// Expect changes here.
///
/// Threading: Not intrinsically thread-safe. It *is* expected
/// that callers will build these objects and then share them
/// via reference counting with the worker thread. The implication
/// is that once an HttpHeader instance is handed to a request,
/// the object must be treated as read-only.

/// Allocation: Refcounted, heap only. Caller of the
/// constructor is given a refcount.
