When time allows or someone pays me to make time. It's certainly fairly
high on the list. But not as high as settling into our new house :)
Tim.
p.s. It'll be done via a new $h->{FetchHashReuse}=1 and it's non-trivial
because the way I intend to do it will make fetchrow_hashref effectively
become an alias for fetchrow_arrayref and thus be _just as fast_.
