Thank you all for your comments!

I'm glad to learn that I was too pessimistic :)

Well, the garbage collector could easily be extended to know about
arrays. But, yes, fragmentation was the main reason for the single-cell
design (especially in the initial versions, when the gc used a
compacting algorithm).

I avoided most argumentation _pro_ lists to keep the article short, and
packed it into the fuzzy statement "... any Lisp programmer will know

Not at all. This was exactly the point. As long as we have 'get' and
other list functions, we can simulate the behavior of arrays.

So, again, thanks to you all for the support! I don't have to defend
that design decision in the future again! :)
