This is silly. Different domains have different needs. If you think of arrays as pointer + offset calculation, and your only for loop has an explicit index increment in it, then starting at 0 is natural. If you are a systems programmer then a language targeting you should accommodate that.
If you are anyone who doesn't want to care (too much) about how things are implemented, then it's a lot less error prone to mark the 1st element of an array a[1]. Having taught and written fairly complex scientific code in both 0 and 1 indexed languages, there really is no good reason to do anything else.
for a in array[3:6]
Should iterate over the third to sixth element of the array.
Nah everyone should just listen to the mathematicians and allow for arbitrary index sets.
Seriously though you save yourself a lot of trouble if you don't worry that much about what range your indices have but rather what they represent. The fact that they're integers starting at 0 is just an implementation detail.
