I agree this can be confusing. I haven't read the documentation  
recently, but I remember being caught out in the past when the docs  
implied that arrays could have "numerical" keys. I was under the  
impresson that deleting a key from such an array would re-order the  
key numbering, but, of course, it didn't.

I wouldn't like to get into a discussion about whether this is a  
"proper" array. The term "associative array" is pretty widely used,  
and it's an extremely useful tool. It would be nice to have standard  
arrays too, I guess, but if we can only have one type, I'll vote for  
what we have now.
