it is a List-like interface to immutable unboxed arrays with 0-based
indexing, which will be used in PackedString.Latin1, PackedString.UTF8
and, if this type will be parameterized with base type, as i
suggested - in all other PackedString implementations and will be
also useful for other libs/apps
... btw, faking List interface is a "poor man classes" solution. at
least in Haskell 2 we need to create Collection classes hierarchy.
even C++ has such beast!
