Just FYI, ages ago I wondered if it would be a good idea to make an
underlying "blob abstraction" that's a pointer, a size, and a custom
freeing function, so it can wrap malloc()ed memory, mmap()ed memory, and
whatever other special things might exist.

Then have blobs, strings, srfi-4 vectors, and friends all have the
option of being a reference to one of the above with an offset and
limit, so they can be views into arbitrary data from external sources.
