Should i read this as +1 for changing to 0-based indexing in watir? For
both (:index, n) as well as table indexing?

For me, I find it hard to explain 0-based counting in data structures like
arrays to beginners, and then have to change gears and tell them that when
they use an index, that it is 1-based. There are pros and cons to both, but
I think when programming in terms of 0-based. Actually, programming has
completely ruined my mental model for 1-based counting in general. :)
This is probably something beginners have less of a problem with at first
than people with programming backgrounds, but the inconsistency is what I
think feels wrong.
