I have a series, that I will try to get posted tomorrow, where I add a new
attribute `ignore-index` which can be used to mark indexed arrays where the
index is just an incremental value. This is a follow-up to an earlier
discussion[1].

In that series, in order to add the new attribute to the existing specs,
in the commit messages I walk through all the existing indexed arrays,
and also include things like if they start their indexes from 0 or 1.
