Not without considerable pain.  There is no invocation to bring in SRFI
4 that works on even a majority of Schemes, so I would have to look up
the docs for each one, and there are currently 45 of them.  What's more,
it's trivial to implement SRFI 4 on top of R6RS bytevectors or vice versa.
What's more, it's straightforward to support either on top of pure R5RS
vectors, modulo the type predicates.
