Strange array behavior

[Richard Gaskin]

In addition to deleting the keys did you also put empty into the variable?

I'm no expert on those, but I think that once a var is used as an array 
it remains one until you do something else with it, even if it has no keys.

It's kinda like a bookshelf containing boxes: even if you remove all the 
boxes, you still have the bookshelf.
