Yes, I will.

So we shouldn't make the list the first argument...

RFC 203 defines a :bounds attribute that defines the maximum index of each
dimension of an array. RFC 206 provides the syntax @#array which returns
these maximum indexes. For consistancy, the arguments to reshape() should be
the maximum index of each dimension. A maximum index of '0' would mean that
that dimension is 1 element wide. Therefore '0' can not be special in
reshape(). Therefore we should use '-1'.

Let me know off-list if you'd like more clarification.
