I can't speak for 'everybody' :-), but Claw has had a package like this for
years.

The Claw package puts the stream element array inside of the wrapper type.
(The access discriminant is interesting, but it couldn't be used on slices
or any constrained object, which would make it annoying to use.) That makes
it a buffer. Usually, it is used by 'loading' the buffer by calling Write
explicitly, then using the stream routines to read from it. (Or vice versa).
