Then would you say it is debug info?

Why is stderr not a good place for this? hash -l documents that its
output may be reused as input, which assumption breaks down if the hash
table is empty.

If "send the non-eval'able diagnostic output to stderr, separate from
the eval'able output stream" isn't a convincing argument to you, then
perhaps it could be prefixed with a "#" such that eval'ing it would skip
that line?
