Will do.

I probably will not, because
1. I don't think it would be very useful.
2. The purpose of this SRFI is to extend list procedures with start and
end arguments, but the proposed procedure would not be able to take such
arguments (or if it did, it would presumably act like the regular
list-copy in the SRFI).
