I'm only half-heartedly continuing SRFI 43, in the hopes that a much
better
collection system will be sorted out (sooner rather than later).

But even so, I've taken several of the suggestions people have made and
produced
a new, much smaller draft, along with a reference implementation --
removing
useless functions for vectors (e.g., VECTOR-UNFOLD,
VECTOR-(FIRST|SECOND|...),
all of the avector functions), some of the downright silly ones (e.g.,
VECTOR-NONEMPTY?, VECTOR-LAST), and put in a few new, useful ones
(VECTOR-RESIZE, as mentioned in a Usenet thread recently;
VECTOR-BINARY-SEARCH;
and VECTOR-INSERT! and VECTOR-DELETE!).

Until I figure something out about using the SRFI CVS stuff (which I'll
contact
Mike Sperber about soon), the new draft and reference implementation
will be at:
