Re: Revenge is a dish best served cold (arrays and 8 queens)

<<It remains to be seen which problem cannot be solved in Prolog

languages or accessing certain API, for example.>>

From what I have seen, there are few problems that absolutely require
particular data structures (hashes, trees, arrays, queues, stacks,
heaps, whatever) in order to be solved. Most (if not all) problems
can be solved with any "basic" data structure, whether an array, list,
or whatever.

So for me, the question is not "whether it remains to be seen which
problems cannot be solved in Prolog without data strucrure X." It is
a matter of having a variety of data structures to choose from in
approaching a problem. Other languages can get by with only a single
data structure as well - a list for example. But they choose to
provide more. Why?

Your car, for that matter, provides many gears in its transmission.
Why? It remains to be seen which car driving problem cannot be solved
by 1 single gear - "first gear." Yet there are usually more provided.

Just my 2 cents.
