This sounds interesting.

From your article:

typedef flex_string<
    SmallStringOpt<char, 5,
        CowString<char, AllocatorStringStorage<char,
std::allocator<char> > > >
> String;

This is a mouth full. Is there a way to present the
various end-user types in a concise way?

I just tried this:

  template <typename A, typename B>
  struct generic {
    A a;
    B b;

  template <typename A, typename B = int>
  typedef generic<A, B> specific;

EDG245 barfs, as expected. Is there a way to achieve what
this example attempts?
