Well, I'm documenting them at the module level, which is where some
doc on them already exists (I'm just embellishing a little for
increased clarity) and what I _think_ "we" agreed on as "what to do"
to document constants, so I don't need/want you to ("promote" them,
that is), but if you decide that you want to do it, I'm neutral
(unless it would hurt performance of course). Thanks for the
additional info,
DG
