A bit off-topic...

Hmm.. byte-vector strongly suggests it's an array of bytes,
implying indexed access is O(1). I think it matches the
practical use of byte vectors (such as dealing with contiguous
region of memory).

On the other hand, a string is a sequence of characters, but
it doesn't need to be an array of characters---it may
internally be a list of characters, or a balanced tree, or
something else.

So byte<->vector and character<->string aren't parallel, IMHO.

To return to on-topic, I'm +1 to byte-vector.
