I didn't realise that we were still in LC mode so I already answered
it directly. Hopefully I didn't say anything too controversial. In
case you missed it, my answer was:

Gary already asked a follow up question. This doesn't really seem to
be a LC comment so much as a request for help from an
implementor. Should I suggest that we move the discussion elsewhere
(where?)  and then answer his follow-up?
