VECTOR-MAP/INDEX is underspecified: it doesn't really say where in the
argument sequence the index appears.  The reference implementation
says it's the last position.  Let me suggest it should be the first:
all variable-arg Scheme library procedures I know assign special
meanings to argument positions from the start, not the end.

Yes, I noticed this...and I mentioned it on the list a few emails ago.
I suggested that it come first, too, and asked whether or not this
change was OK with them; since you're the only person to have said
_anything_ on this list since my last email one and a half months ago,
I think the change _is_ OK.

PS: While the draft period is somewhat overextended on this, I only
just now started some more extensive hacking using vectors which
prompted me to have a closer look at the SRFI 43 draft.

Too bad you hadn't done this extensive vector hacking back when the
concept of a draft period still occurred to some of us...well, do you
have opinions on the past few issues that I've brought up, namely the
things regarding VECTOR-COPY!, the insertion & deletion routines, and
the issue regarding start+end versus N vector arguments?

Let me say that the stuff there is very useful, even in the face of
the nebulous hope for grand unified collection ... something.  Good
work, Taylor!

Thanks!
