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.

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.

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!
