Hi all,

I'm going to try to give a preliminary response to review feedback while
James is away, to help move this series forward.

Many thanks to those who have reviewed / commented so far!


Apologies for the slow-ish response from me: I'm still not that familiar
with this code, so I wanted to make sure I had broadly covered most of
the simpler comments before I started sending replies.

N.B.: where I say "Noted", I mean that I've stashed a fixup for James
to review when he gets back. Most of these seem straightforward and
uncontroversial, but it's his code, so it will be up to him what
changes actually get incorporated in the respin.

Cheers
---Dave
