I chose that doc ordering for clarity, the easy ones 1st,
and @dst last since it gets the subrange info.
I think reordering might mean more words trying to connect
the pieces, and with less clarity.
It does work against the macro arg ordering,
which places @dst near the front,
I did that to follow LHS = RHS(...) convention.
Im happy to swap it around if anyone thinks that convention
should supercede these reasons,
but Im in NZ on vacation right now,
and I forgot to pull the latest rev off my desktop before I left.
so I dont want to fiddle with the slightly older copy I have locally,
and then have to isolate and fix whatever is different.
the same applies to the Documentation tweaks that Bagas noted.
