-- Secret values
--
-- Since 11.2 the game hides information the player isn't supposed to automate
-- decisions on (dungeon/raid loot being the common case) by returning "secret"
-- values instead of real ones.  A secret value can be passed around and stored,
-- but tainted (addon) code can't compare it, do arithmetic on it, concatenate
-- it, take its length or use it as a table key -- all of those raise an error.
-- Anything coming back from the game therefore has to be checked before it's
-- used, and the check has to come before any other test (including a plain
-- truthiness test) since that's an inspection too.
