rob_au,
Instead of adding it, I have updated the node to remove exists in that section as it was not necessary. It did not occur to me that novices might see exists as improper with an array and total miss using a string as an index.

While your point is well taken, I believe "Autovivication Pitfalls and How To Avoid Them" deserves to be a tutorial all to itself.

Cheers - L~R

    [Corion]: I think there's always some Dell coupon around, at least I got one the last two times I bought a machine from them
    [1nickt]: I have been an apostate in the Apple orchard for almost 15 years. But Dells are still high quality it seems, unlike Macs these days.
    [1nickt]: And you can still configure the system at will, on the "Small Business" site.
    [Corion]: 1nickt: I bought a 2015 XPS 13, which is a very nice and shiney (and somewhat overpriced) machine, but I think it's still better priced than an Apple machine. Now it just has to hold up 10 years like the old one did ;)
